How To Use Legs In Swing Like Rizzo, Altuve, & Trout

Answered: “How To Get My Kid To Stop Rising And For Him To Utilize His Legs More During Batting?”

 

 

Here’s what we cover in the above video:

  • Legs DO NOT equal power – water polo example,How To Use Legs In Swing Like Rizzo, Altuve, & Trout
  • What is leg function in swing & Adjusting to pitch height,
  • Distance between the feet equal more control over line drives,
  • GRF’s but not as much as you think,
  • Buying time – back foot sideways, directional force, & pushing the “pause” button, and
  • How to utilize the legs in the swing?

Hey, what’s going on. It’s Joey Myers again from ‘Hitting Performance Lab’. In this video, we’re going to answer the following reader question:

“How to get my kid stop rising, and for him to utilize his legs more during batting?”

Now this is a question that comes either through a form, survey, or email or even from my local lessons. The coaches out there in the high schools tend to meddle a bit too much, subscribing to the hitting myth that: ‘it’s all about the legs’, or ‘you need to use your legs more’.

In this video, I want to talk about what that means, and what is the function of the legs…

 

Legs DO NOT equal power – water polo example

Legs are only 20-30% of the consistent power equation, and most of that is in the function of the pelvis.  If you’re a coach and power is the deficiency in your hitter’s swing, then it’s the spinal engine you want to focus on.  The Catapult Loading System is where 70-80% of consistent power is found.  The best example I like to share can be found in water polo.

And my favorite demonstration to do for hitters is showing what a beach towel and the spinal engine have in common.

 

What is Leg Function in Swing & Adjusting to Pitch Height

Now a couple things, one is they help to adjust to pitch height. If you’re looking at hitters like Cody Bellinger of the Dodgers, Joc Pederson of the Dodgers, Corey Seager, looking at Anthony Rizzo of the Cubs or some of the past players like Adrian Beltre or Pedroia. When the pitch is down in the zone, you tend to see them bend their front knee to go down and get it. They tend to do that consistently on those pitches, those lower in the zone pitches, not locking out their front knee like many teach.

I’ve seen these same hitters Rizzo, Bellinger, I’ve seen them with a bent front knee hit balls 440 to 460 feet.  So, locking out the front knee IS NOT all about power.  So, this raises a question of, if you want a hitter to use their legs more often because you think it has to do with power, well that is just not true – that’s not what we’re seeing. So, adjusting to pitch height, and you can study the hitters discussed as examples.

 

Distance between the Feet Equal more Control over Line Drives

Distance between the feet, this is a big one, that we can use the legs or utilize the legs to allow hitters to hit more line drives. The problem happens when, say if we are teaching our hitters to skip their back foot that they end up skipping their feet too close together.  Or it could be they don’t stride that much. They don’t skip at all and, so their feet tend to be closer together. What we want is what you see with the top 50, top 100 hitters in the big leagues….

You’re going to see distance between their feet. So, whether that is a longer stride and their front foot moves away from their back foot. Whether they don’t skip but they don’t stride as much, you still see that wideness of their feet. You see them scissor, you see different things like that, but what they all have in common, all the top hitters in the big leagues, is they have distance between their feet.  When the feet come close together, it makes the hitter taller, which this reader is asking how to keep the hitter from “rising”.  The taller the hitter gets, the more in the ground the ball is gonna get hit.

If the hitter knows better, and they try and get the ball in the air, even though they have narrow feet during their turn. Then they’re gonna do something unnatural with their hands to try and get under it, which we don’t want them to do either. Because that is going to cause uppercuts.  It’s going to cause inconsistencies in their swing path.

 

GRF’s, but not as much as you think

I just mentioned that hitters don’t have to lock their front knee out for power. When you think about ground reaction forces (GRF’s), they DO play a role. I’m not taking away from ground reaction forces, or saying “Oh, well the legs don’t do anything in the swing”.

No, they do. It’s about a 20 to 30% increase in power by using the legs. Most of that though is in the pelvis, and the rest in the spinal engine. I tell my hitters that the spinal engine, their combination of your shoulders and how you use them.  Neck, shoulders, and pelvis account for about 70 to 80% of the power. That gets you to the wall. The legs help get you over the wall. So, you do need the legs, and it’s like what Dr. Serge Gracovetsky, the author of the Spinal Engine said, that locomotion, the arms and legs aren’t necessary for locomotion, they’re an enhancement, they help enhance movement of the spinal engine.

So, we’re not taking away from the legs, the use of the legs, and how they can benefit the swing. It’s just that they’re an enhancement to the spinal engine, the taller the player is, the longer the levers, the more the force multiplier at the end of that lever. So, guys like Aaron Judge and Giancarlo Stanton are gonna have longer levers, if they lengthen those levers at impact. When we’re talking about the front arm shape, they’re gonna hit the ball pound-for-pound, apples-to-apples swings farther than Jose Altuve with the locked out-front arm. It’s just because the longer limbs enhance more, they’re more of a force multiplier.

 

Buying Time – Back Foot Sideways, Directional Force, & Pushing the “Pause” Button

Buying time. So, the lower half, the legs can help buy time. Jamie Cevallos in his book Positional Hitting way back, I think it was in the early 2000’s or mid to late 2000’s. He talked about this idea of a ‘Cushion’. You’ll see a hitter especially, if they’re looking fastball, and they see a curve ball or changeup. You’ll see them actually bend, sink, or cushion into their knees. They use their knees by bending them to buy them a little bit of time to get on time a lot better.  It’s pushing the ‘pause’ button.

The other thing we want to do to buy time, is keep the back foot sideways.

We talked about this idea of directional force, Matt Nokes, he says that to hit a ball 400 feet, it takes 8,000 pounds per square inch of force in one direction. In hitting, both in baseball and softball, we have 90 degrees to work with. The other 270 degrees is in foul territory, it doesn’t do a hitter any good or a team any good to play in that 270 degrees outside of a fair territory. We have to stay between the 90s, we have to stay between the lines. If you think about a bowler, every single professional bowler out there, “scissors” their legs.

I’m not saying that all hitters have to scissor. I just give my hitters that option.  But if you think about bowlers, they bowl between a two-foot Lane. I don’t know if that’s correct or not, but it’s somewhere around that. They also put a spin on the ball, so if they over rotated their lower half, not keeping their back foot sideways, they’re over rotating their pelvis. Then what you would see is that ball bouncing into the outside lanes.  Try scissoring your legs, then try and open your hips up more, and it’s almost impossible.

You want to make sure that we’re creating directional force, and that’s another thing the legs do. They help us stay between that 90 degrees, and use all 90 degrees effectively. That comes in handy at the higher levels when hitting to the opposite field is a lot more important, and when we see shifts.  Most of the time, hitters are not very good about going the other way. You can see the hitters that do go the other way very well, their batting averages seem to be higher.

 

How do we Utilize the legs in the Swing?

Now again, if it’s power you want, this isn’t the place. You want to look at the Catapult Loading System, and harness the power of the spinal engine.  If you want a majority of power, 70-80% of consistent power.

Getting Shorter, Staying Shorter

To properly utilize the legs in the swing, you want to look at getting shorter and staying shorter.  You see most great hitters when you draw a line over their head before they stride, by the time they get to stride landing, you’re gonna see distance between where they started, and where their head is at stride landing. You’re gonna see what we call ‘Getting Shorter’.

Then as they swing, it’s almost like that bottom ladder rung they create at landing, they tend to stay under that line. What we do is, we could take a PVC pipe. We can put it at the start of the hitter swing, before they even stride…we can put it maybe at their nose or their chin, and we can have them practice getting the top of their head under that PVC pipe. As they swing, stay under that PVC pipe. I’ve also had my hitters get next to a piece of furniture that’s about the same height, then have them stride, and get their head to where, now they’re under the top of that, say dresser or whatever, or picture frame, could be anything around the house.

When they swing, do some slow motion swings, and they stay under that line. That’s a way to get shorter, stay shorter.

Okay to “bend the knee”

It’s okay to bend the knee, I also get my hitters to do this if necessary. We don’t really practice this, but I tell them it’s okay to bend the knee, if the pitch is down in the zone.

Distance between the feet

Also working distance between the feet, you can either get them to stride longer, or you can cut down on their skip. We usually try to manipulate one of those two things or both things to get that distance between the feet, so that allows them to hit more line drives or at least control their line drives.

Keep back foot sideways

Then keeping their back foot sideways. You can use the VeloPro, they use it in pitching a lot. But in hitting, we use the VeloPro.

We tell the hitter to make sure they keep their back foot, their back heel on the ground as they swing. Almost like you would see with George Springer, or Altuve, or Mike Trout, any of those kinds of hitters or in softball Sierra Romero. They keep their back heel on the ground and it turns sideways, so they stay sideways. They do a better job of staying between those 90 degrees.

One last thing on keeping the back foot sideways, as mentioned, scissoring helps with that as well. So, that’s something that you can play around with, and let your hitters’ experiment with.

Hope this answered the question of “How to get my kid to stop rising, and for him to utilize his legs more during the swing”. Make sure that we’re swinging smarter by moving better, and before I let you go…

Answered: “Helping Get Youth Players To Stay On Plane And Not Dip Their Bodies When They Swing?”

 

 

In the above video, we’ll be discussing:

  • Relationship between spinal engine and shoulder behavior in healthy effective swing,
  • Causes of unhealthy “dipping” of body in swing,Do You Recognize The 6 Early Warning Signs Of Hitters Dipping Their Bodies?
  • Head stability,
  • Arching low back,
  • Straightening out back leg,
  • Over-rotating upper half,
  • Over-rotating lower half, and
  • Core instability.

Hey, what’s going on. It’s Joey Myers again from the “Hitting Performance Lab. In this video, we’re gonna answer a reader question, this one is asking for advice to:

“Helping get youth players to stay on plane, and not dip their bodies when they swing”.

Now a couple things we have to define here, what ‘dipping’ is…

 

Relationship between Spinal Engine and Shoulder Behavior in Healthy Effective Swing

This is important to cover. Because there is some dipping that goes on, but I want to define what’s good versus what’s bad. What we should see with hitters, and good healthy spinal engine mechanics is, say with the righty, the shoulders will start in somewhat of a slightly down position, we call this the ‘Downhill shoulder’, and it’s just a side bend.

David Weck, founder of the BOSU ball, the RMT Club, and a lot of other cool stuff. He talks about this idea of the head over foot technique. The head shifts slightly over towards the front stride landing foot.  The side bend is crucial to the actual opposite action that’s gonna happen during the swing.

We’re gonna see the teeter totter effect of the shoulders starting down, and then they’re gonna flip up as I start my turn. Then what we should see is this shoulder, if we track the left one for a righty starts down, pops up. As we finish, should be back down again.  Think about those beautiful images of Mickey Mantle, Ted Williams, Babe Ruth, Lou Gehrig, in their finish, and the righties are kind of in this position. The lefties are in the opposite position.

We want to see a healthy accelerating-decelerating spinal engine, that is the healthy dipping that we should see if the shoulders or side bending.

 

6 Causes of Unhealthy “Dipping” of Body in Swing

1. Head Stability

I call it a ‘Collapsing backside’, so one of the causes of this is head stability. We’ll see a hitter will go chin to chest, when they’re at impact, going right into their sternum with their chin. Sometimes we’ll see the head go up (like looking up into the sky), we’ll see the bill of the cap go this way, and we’ll see the rear ear going to the rear shoulder, so for righties, right ear to the right shoulder. For lefties, left ear to the left shoulder.

There are some hitters in the big leagues that do this a little bit, they used to do this actually more in the past, they’ve been cleaning it up. But Andrew McCutchen used to go chin to chest, Bryce Harper would go rear ear to shoulder, Prince Fielder did what Harper did.  You even see Nolan Arenado more chin to chest. Because he tries to leave his head at impact, which I don’t recommend for younger hitters. When the head is in an unstable position, this creates a threat to the central nervous system. Wherever the head goes, the body follows.

If the head “rolls” (like Harper/Fielder)…when we’re rolling the head this way, you’ll see a collapsing of the backside, you see the whole body will dip, and it’s not a very strong position. Head stability is one of them, one of the causes of an unhealthy dipping of the body in the swing.

2. Arching low back

Arching the lower back, kind of similar to the neck, the C-spine. When we start arching the lower lumbar during rotation, which isn’t very good because you’re pushing the vertebrae together, and then rotating them, so you’re basically grinding. So, we don’t want to do that, and if we’re doing that, sometimes we’ll see this collapsing to the backside as well. You want to do it what’s called a ‘Hollow position’, or a ‘Hollow hold’, you can go on YouTube, and search “hollow hold gymnastics”, and you can find a video on how to practice this.  It’s basically taking the curve out of our lower lumbar, or lower back.

Imagine you’re lying on your back, on the ground, like you’re gonna do a crunch, you got your feet on the ground, your knees are up, and you go to do a crunch. What you have to do first is push your lower back into the ground, just want to push hard in the ground, create some pressure into the ground through your lower back.  That’s taking the curve out of your lower back, and doing what we call a hollow position. It’s a posterior tilting of the pelvis for those kinetic nerd jockeys like me.

3. Straightening out Back Leg

The other thing that could be causing dipping of the body in the swing is straightening out the back leg.  This tends to follow both head instability, and/or arching of the low back.

The glute fires, the back glute, for righties the right glute, and the right quad fires to straighten the knee. It’s the hamstring that we see in professional studies of hitters, back hamstring that’s turning on a lot more than you see in amateur hitters, where they tend to try and lock that back knee out. The glute locks out, and what’s happening is that back glute is trying to support and create stability in the lower back. Because it’s going into a bad position, a compromised position. As long as we can fix the hollow, get them into more of a hollow position, we fix the head movement with the neck brace drill. Not a stiff neck brace, but a soft one.  We don’t want to immobilize the head, just create feedback for movement.

If you can correct this, you can crack the lower back – metaphorically speaking of course – then you can start to work the hitter into bending that back knee a little bit more, using the hamstring, lesser the quad, and lesser the glute. Those are again trying to protect that lower back, that can be a major cause of unhealthy dipping in the swing.

4. Over-rotating Upper Half

I am starting to actually see this in some of my hitters, not in a lot but a few of them.  Where they’re actually over rotated at impact. They’re making contact almost behind themselves, and their sternum in the middle of their chest is out over in left field (for righties, reverse for lefties). We must get them to under rotate, so we do a lot of “deep” tee drills, and get them to try and pull the ball off a deep positioned tee. You set it up almost in line with the hitter’s belly button, and get them to kind of hook it, and hook it around to slow down that sternum.  The hitter should look and feel like they’re swinging their arms across their body. 

The upper half over rotating, we can also over rotate the lower half…

5. Over-rotating Lower Half

So, we use a VeloPro to strap it to the back hip and back ankle.  We get them to try and keep the back heel on the ground (like George Springer), and keep the back foot sideways. If they’re over rotating, it could cause a collapse of the backside as well. Again, we want to be effective between our 90 degrees of fair territory, and when we over rotate either the upper or the lower half, then what we’re doing is we’re sliding our 90 over into foul territory, which doesn’t do us any good, any of our hitters any good.

The last thing I want to add in this video is fixing core instability…

6. Core Instability

There are things that you can do at the gym with your trainer, hopefully your trainer is versed on mobility and stability exercises (certified in the Functional Muscle Screen – FMS, or in TPI). When we’re talking core stability, you want to do a lot of things like planks:

So, you’re creating some rotation in there as well. You also want to do like ‘Hollow holds”, you want do things like that, you want to do maybe suitcase carries, where you’re carrying a dumbbell on one side of the body and trying to keep your shoulders square, things like that you can do. You can ask your trainer on how to create more core stability, but those are some things to think about if you’re asking yourself the same question as our reader: “Helping get youth hitters to stay on playing, and not dip their bodies when they swing”.

Work on the things we discussed, clean them up, and check them off your list. Your hitter will be in a more healthy body “dipping” position. Make sure that we’re swinging smarter by moving better, and before I let you go…

Why You SHOULD NOT Use “Forearm” Or “Barrel” Cues In This Way…

Lower Back Explosion Extravaganza

Tweet from a #HittingTwit-ter

We have a lot to cover in this post, so this is what we’ll be discussing:

  • Here’s the problem…
  • Short anatomy lesson of the low back, and
  • What’s the answer?

Most “bad” coaching cues I see out there can work in the right circumstances, for example:

  • “Swing down” – can work for hitters who have an extreme uppercut…
  • “Sit back” – can work for hitters who are too far out front…
  • “Swing up” – can work for hitters who have an extreme down swing…

 

But Here’s the Problem…

I’ve been tracking the above swings cues for some time now, and I’ve found in a majority of cases, they seem to churn out one low back ticking time 💣 swing after another.  When I see one of these swings on Twitter, it’s like listening to grinding teeth, someone’s fat lips smacking while eating, or nails on a chalkboard.

Let me show you what I’m seeing…

Lower Back Exploding Extravaganza

Compilation of low backs exploding…

How do I know the above hitters were instructed with the coaching cues in question?

These were the hitters on proud display via the Twitter page of the above instructor’s name I blurred out!  Now, he’s not alone in this.  Many others like him are following the same blind mouse.

Btw, it wasn’t hard to find ANY of these swings…I found them in a matter of minutes.  And to be fair, not ALL this instructor’s hitters were doing this, but close to a majority.

Here’s one more clear swing example, one of my readers Shawn Bell shared after seeing the video above…

Focus on nothing else but her lower back…OUCH!

Fact: hitting cues have consequences. When we teach a hitter to take focus away from basic locomotion and gait principles, and put it squarely on manipulating the “forearms” or the “barrel”, young hitters will have a higher probability of wearing a hole in their low back than not.

“Unload your barrel not your body”…

AND,

“The forearms swing the bat. The body helps”…

…are misleading at best, and not having a clue as to what drives ALL human movement.  And these instructors routinely call this a High Level Pattern (HLP).  Sad.  All I see are low backs grinding.  To me, this is a Low Level Pattern (LLP), disastrous to young moving bodies, built on a stale straw man argument, losing sight of the forest for the trees, and chasing a sunset running east.

And most importantly, this low back ticking time 💣 IS NOT found in the REAL High Level Pattern.  I challenge you to find me at least one who does this…and if you find one, I’d love to dig into his or her history of injury.

 

Short Anatomy Lesson of the Low Back

Lordosis of the Spine

Photo courtesy: MountSinai.org

Normal lordosis of spine (natural low back curve – “neutral” spine), left hand side image.  And hyperextended lordosis (or arching) of spine, right hand side image.

Arching causes the vertebrae in the spine to push together.  This isn’t damaging by itself especially when done in global extension (think gymnast swinging forward under the bar), but adding in a little rotation over and over and over, and we have a low back ticking time 💣.

The REAL High Level Pattern (RHLP) is driven by the spinal engine.  Basic principles of locomotion and walking gait.  I would feel MUCH better reversing the two quoted coaching cues above to read…

“Unload your body not your barrel”…

AND,

“The body swings the bat. The forearm helps”…

This is a RHLP.  As Dr. Serge Gracovetsky (Physicist and Electrical Engineer), author of The Spinal Engine book says:

“The arms and legs aren’t necessary for locomotion.  They’re an enhancement.

Do you want proof to validate this statement?  Watch this… (Thanks again Shawn Bell for the giphy)

  

…The gentleman in the above video is from one of  Dr. Serge Gracovetsky’s movement experiments.  He was born WITHOUT arms and legs.  The crazy part is, if you block out his black shorts with your hand, and look at the way he moves and locomotes, you’d swear this man has legs.

The low back ticking time 💣 risk hiding in your swing can be found in using “forearm” and “barrel” focused cues.  The proof is in the almost dozen swings I found in the matter of minutes on Hitting Twitter.

And if you still don’t agree, then here’s one of my other favorite quotes from the author of Atlas Shrugged, Ayn Rand…

“You can avoid reality, but you can’t avoid the consequences of avoiding reality”.

 

So, What’s the Answer?

A safe AND effective swing.  If we’re ruining lower backs, then how effective is effective?  Here’s a clue, instead of arching the low back, what happens if we do the opposite (flexing v. extending)?

I’m glad you asked!  Think about flexing the lower back as putting space between the 5 vertebrae located there.  This keeps the body from putting a death squeeze on the squishy and lubricating material between the vertebrae (cartilage and synovial fluid).  It makes the spine SAFE for rotation.  You got it, NO MORE LOW BACK TICKING TIME 💣’s!!!

So how do we protect our hitters and build a SAFE and Effective Swing? 

Think of your pelvis like a bowl of water.  Now, imagine a “Donald Duck” butt, where you’re sticking your butt back (arching low back – Dr. Kelly Starrett in his book Becoming A Supple Leopard refers to this as “Nasty Stripper Pose”).  For the kinesiology nerds out there, this is an anterior pelvic tilt – spilling water on your toes.  This IS NOT a good pelvic position when swinging a bat or throwing a ball.

Now, doing the opposite, imagine that same bowl of pelvis water in a posterior pelvic tilt, or Pink Panther butt, think about spilling water on your heels.

I have some cues you can use with your hitters, and a couple Hitting Performance Lab resource posts to reference…

The Hollow Hold…

If you’re one of those LLP instructors, and still aren’t convinced…PLEASE, PLEASE, PLEASE for the love of God…at least strengthen your hitter’s in the Hollow Hold.  I’m tired of seeing all the low back ticking time 💣’s waiting to go off. You’ve been WARNED.

 

In Memoriam

This post is dedicated to a great friend of mine and fellow baseball coach that we lost to a brain aneurysm on Monday… (my Facebook post):

“Words cannot express my deep sadness today upon hearing of my good friend and fantastic coach Sam Flores’s passing yesterday. He had no idea he was in a fight for his life – and would lose it – driving to the hospital with his family. So young. So tragic. My family and I ran into him at Costco 4 short weeks ago where we had a brief catch up on life and a big hug…you just don’t know when someone’s time is up. Hug your loved ones today, keep them close, and realize God is in control, not us. We love you Sam, and send my BIGGEST thoughts and prayers to your family as they go through the tragic mourning of your passing. The valley lost a wonderful Father, Husband, Friend, and ultimately a brilliant Coach. RIP my good buddy you will be missed (breaks my heart to see that little kiddo of yours) 😢😢😢

Demonstration On How To Take “Slack” Out Of The System (and what it means)

Here’s a great way to help coaches and players understand taking slack out of the system, demonstrating the power of the spinal engine.

We call it the “coiling” core, NOT the “braced” core most teach their hitters.  A braced core is fantastic in the weight room, but NOT in the Spinal Engine - Wringing Towel Out Demonstrationbatter’s box.  CLICK HERE for an interview I did with Bosu Ball inventor David Weck, where he takes a deeper dive into this.

Some understand the importance of shoulder-hip separation, but what most don’t know is that we MUST create tension in the neck – where the ‘C’ and ‘T’ sections of the spine connect, as well.

And here’s what most ARE NOT saying…an inward turn of the hips is not important, if not detrimental, to the beach towel effect of the spinal engine.

Many say the swing of Ted Williams resembled the twisting of a Barber Pole.  The above video clearly demonstrates what was happening in his swing that some observed.  CLICK HERE for a post I did on the swing of Ted Williams.

Best Swing in Baseball: Here is a Method Helping Mookie Betts – And Many Others – Consistently Crush The Ball

 

In this best swing in baseball video, we’ll discuss:

  • Data and reasoning because personal opinions are seldom useful,
    Best Swing in Baseball: Mookie Betts hitting inside pitch and 'showing numbers'

    Mookie Betts (via my Twitter feed) ‘showing numbers’ at landing on inside pitch…Hitting Guru #57 “should NEVER ‘show numbers’ on inside pitch” objection based on personal opinion with ZERO data to back claim :-/

  • Anatomy Trains, The Spinal Engine, Dynamic Body, WeckMethod, Matt Nokes, Homer Bush, Aaron Miles, and numerous past and present professional hitters agree with CLS,
  • Objection #1: Increases Time to Impact because turning away from impact – twisting balloon analogy,
  • Objection #2: Hitter loses vision and tracking of the pitch – “back eye test
  • Objection #3: Not on inside pitches – hitting “belly button” catcher’s glove,
  • Can eat soup with spoon, fork, knife…but only one way is more effective. Teaching hitting is the same.  Apply human movement principles that are validated by REAL science, NOT “because-I-said-so ‘bro-science'”, and
  • The information is out there, so hitters will find it for themselves, either you will be able to take credit for teaching it or you won’t. Results don’t lie.

Still don’t believe the best ‘show numbers’?  CLICK HERE for a post I did recently titled, “Why I Teach Hitters To ‘Show Numbers’ (And Maybe You Should Too)”.

Don’t be like opinion-based Hitting Guru #57…have solid data and reasoning to back up your “opinions”.

‘Showing Numbers’ to Pitcher is a Quick Way to Solving Consistent Power Problem

 

Question: How does ‘Showing Numbers’ to the Pitcher Effect Bat Speed at Impact versus ‘NOT Showing’ them?

Aaron Judge Showing Numbers to the Pitcher

Aaron Judge (Showing Numbers), unloads a solo home run to center field on 10/17/17 to put the Yankees on the board in the 7th inning.

Using the Zepp (Labs) Baseball app, I wanted to use the Scientific Method to analyze if a hitter showing their numbers to the pitcher at landing adds to or takes away from key swing performance metrics like Bat Speed at Impact, Time To Impact, and Attack Angle.  This swing experiment is revisiting two other experiments done analyzing the same thing.

 

Background Research

Since we’re REVISITING two previous swing experiments on ‘Showing Numbers’ versus NOT, here are the original posts and data to get you up to speed:

In 2016 ‘Show Numbers’ swing experiment, this was what the averaged out Zepp data looked like:

  • 5-mph INCREASE in Bat Speed at Impact with ‘Showing Numbers’,
  • 0.5-mph INCREASE in Hand Speed Max with ‘Showing Numbers’,
  • .003 second DECREASE in Time to Impact with ‘Showing Numbers’,
  • 3* INCREASE in Bat Vertical Angle at Impact with ‘Showing Numbers’, and
  • 1.5* INCREASE in Attack Angle with ‘Showing Numbers.

Now, let’s see how the Ball Exit Speed averages compare:

  • 76.02-mph BES when ‘NOT Showing Numbers’,
  • 77.32-mph BES  when ‘Showing Numbers’,
  • That’s a 1.3-mph average INCREASE when ‘Showing Numbers’, and
  • Translates between 5.2-feet to 7.8-feet of EXTRA batted ball distance – depending on if you calculate using 1-mph BES = 4-feet of distance OR 1-mph BES = 6-feet of distance.

In this experiment, if you look at the ‘NOT Showing Numbers’ swings, they were actually ‘Showing Numbers’.  In other words, the subject in the swing experiment, Preston Scott, already shows his numbers well causing a challenge to not show them.  Therefore on the ‘Showing Numbers’ swings, he showed them more.  I think that’s why we didn’t see as much of a difference in Ball Exit Speeds.

In 2014 ‘Show Numbers’ swing experiment, this was what the averaged out Zepp data looked like:

  • Bat speed for NOT showing numbers at landing: 73-mph,
  • Bat speed for showing numbers at landing: 79-mph (+6-mph),
  • Highest bat speed for NOT showing numbers at landing: 82-mph,
  • Highest bat speed for showing numbers at landing: 88-mph (+6-mph),
  • Hand speed max for NOT showing numbers was: 27-mph, and
  • Hand speed max for showing numbers was: 29-mph (+2-mph).

Between both swing experiments, we saw an average Bat Speed at Impact increase between 5 to 6-mph.  In 2016 we saw a .003 second drop in Time To Impact ‘Showing Numbers’, while in 2014 we saw a .003 increase.

The research on increasing bat or ball exit speed can be seen in the following two books on springy fascia and spinal engine mechanics:

You can also get application of previously mentioned books through the following HPL video blog posts.

  1. Miguel Cabrera and the timing of torque.
  2. Josh Donaldson v. Jose Bautista: how spine engine mechanics are amplified by Gravitational Forces, and
  3. Adrian Gonzalez: how-to naturally spring load the body.

For those versed in Anatomy, for explosive movement on the Transverse Plane (twisting), there must be a protraction of the front scapula (‘showing numbers’), and a retraction of the back Scapula (what’s often referred to as ‘Scap Row’).  Scap Rowing by itself doesn’t engage full range of springy fascia.

 

Hypothesis

Based on the above research, I’m expecting to see a dramatic bump in Bat Speed at Impact, Hand Speed Max, and possibly a reduction in Time To Impact.  I think Attack Angle and Bat Vertical Angle at Impact will remain unchanged.

 

Showing Numbers Swing Experiment Part-3

Equipment Used:

SwingAway Bryce Harper model

This is the SwingAway Bryce Harper model hitting station used for the ‘Showing Numbers’ experiment.

Setup:

  • SwingAway Bryce Harper bungy suspended ball was set equal to the landing foot, and ball height was about knee height.
  • I broke each swing down into three steps: 1) Get to landing, 2) Pause for 2-secs, and 3) Swing.  The reason for this was to better control whether I was showing numbers or not.
  • The two tests in the swing experiment were counter-balanced.  Which consisted of eight blocks of 25-swings done in the following order ABBA BAAB.  ‘Showing Numbers’ was letter ‘A’, and ‘NOT Showing Numbers’ was letter ‘B’.  200 total swings were completed in the experiment, 100 per test.  Counter-balancing helps remove the “getting tired” and “warm up” factors.
  • The ‘Showing Numbers’ swing shoulders were set to about 2’o’clock, if pitcher is 12’o’clock.  The ‘NOT Showing Numbers’ swing shoulders were set to about 12’o’clock.

 

Data Collected from Zepp Baseball App:

'Showing' v. 'NOT Showing' Numbers to Pitcher Zepp Numbers

Data Analysis & Conclusion

Zepp data analysis comparing the averages:

  • Bat Speed at Impact INCREASE of 3-mph ‘Showing Numbers’,
  • Hand Speed Max DECREASE of 1-mph ‘Showing Numbers’,
  • Time To Impact INCREASE of 0.014 ‘Showing Numbers’,
  • Bat Vertical Angle At Impact DECREASE of 4-degree ‘Showing Numbers’, and
  • Attack Angle INCREASE of 6-degrees ‘Showing Numbers’.

The drop from previous ‘Showing Numbers’ swing experiments was surprising, in addition to a small 1-mph drop in Hand Speed Max.  There was also a slight increase in Time To Impact.  The interesting numbers were the ones that indicate Launch Angles, both Bat Vertical Angle at Impact and Attack Angle.  We hadn’t experienced such a dramatic uptick in those in past experiments.

A couple notes…

  • The past two experiments were done in a cage, off a tee, so I could see ball flight, and maybe that had an effect on the swing metrics.
  • Some hitting coaches speak highly of Time To Impact and want to reduce at all cost, but I disagree. There’s a healthy range for that, you don’t want it too short or too long.  I’m not going to get into why here, maybe in another post.
  • To explain the dramatic increase of the barrel’s upward trajectory in ‘Showing Numbers’, I may have been getting more of a downward shoulder angle at landing.

Controversial Swing Experiment Video: What Happens To Ball Exit Speeds When We Eliminate Use Of Lower Half?

Do you consider yourself an open minded coach?  If not, then this post MAY NOT be for you.

Do you consider yourself a coach willing to try new movements before criticizing them?  If not, then this post MAY NOT be for you.

Fair WARNING…this video will make most feel uneasy because it strikes at the heart of their teaching.  I believe the quality of our lives and the success we experience in it, depends solely on the questions we’re willing to ask our-self.

In this video, the Backspin Tee Gardner Brothers (Taylor & Jarrett Interview here) recently did a small thought provoking swing experiment that looked at how much value the pelvis contributes to the swing.  Most popular hitting instructors treat the pelvis like a JoBu shrine in the movie Major League.  Don’t get me wrong, the pelvis has a role, but I disagree on the importance most put on it.

Using the Scientific Method…

 

Question

Backspin Tee Swing Experiment on Not Using Hips

Taylor Gardner doing a Jumping No Hips Swing

They looked at how much value (measured in Ball Exit Speed) the pelvis contributes to the swing by restricting its movement.

 

Background Research

Taylor read my book The Catapult Loading System: How To Train 100-Pound Hitters To Consistently Drive The Ball 300-Feet, and it got him thinking about how much the pelvis actually contributes to power compared to the shoulders?  Earlier I mentioned how much the movement of the pelvis in the swing is worshiped by so many hitting coaches.  “Fire the hips!” “Hip Thrust baby!” Sadly, the torsional forces are taken to the point of being unhealthy for a young hitter’s low back.

Consider what Charlie Weingroff, DPT, CSCS, a physical therapist and trainer in New York City said this:

“Only your thoracic spine (which consists of the 12 vertebrae in your upper and middle back) is designed to rotate significantly — about 40 degrees in each direction, according to Weingroff — when under compression. The lumbar spine (lower back) should rotate no more than about 12 degrees.”

Let me give a clue, coaches want better separation, torque, lag, etc. in their hitters right?  We see that a high level right handed hitter’s pelvis starts rotating counter-clockwise at the start of the turn, leaving the shoulders temporarily behind, this is the essence of “lag” or “torque”.  But what coaches aren’t seeing is what’s happening before the ‘hips lead the way’?  The compression and tension forces happening in the torso beforehand, to make that move possible.

If hitting coaches would do their homework on basic bio-mechanical locomotion and function of the spinal engine as a whole, then they’d find they’re missing  60-70% of the performance puzzle (as you’ll soon see), and quite possibly wearing a hole in the lower backs of their hitters.

I constantly see well intention coaches posting videos on Twitter of their young hitters savagely twisting the pelvis and low back (lumbar), in addition to the hyper-extension of the lower lumbar.  Quite frankly, it’s painful to watch.  CLICK HERE for an exercise to correct this.

Did you know there’s a much safer way to achieve those high BES numbers and more?  Some books to get you started on the right track:

By the way, Dr. Serge Gracovetsky is a Physicist and Electrical Engineer.  He said the Spinal Engine can operate in space without Gravitational Forces.  His research shows arms and legs aren’t necessary for locomotion, they’re an improvement.  Please read that sentence again because it’s important to understand locomotion.

Can explosive high level athletes perform without the aid of Gravitational Reaction Forces?  Check out the following videos:

Derek Jeter makes jump throw…

Jeter is jumping up and away from his target, taking his momentum in the opposite direction of first base. This should put him at a disadvantage, but it doesn’t hurt him too much, as you can see.

Big air motocross freestyle jumps…

Notice how these athletes use the head to control their body.  No Gravitational Reaction Forces to help here either.  But man can these athletes put a big smile on your face while watching this video!

Don’t seek the footsteps of others, seek the footsteps they sought.

 

Hypothesis

The Gardner brothers thought this mini swing experiment would show more of a minimal role of the pelvis in the swing, compared to the “pelvis worshiping” hitting coaches out there.

 

Experiment Setup Details

  • 4 different hitters (Taylor – High School level hitter College Track & Field athlete, Jarrett – professional pitcher, Rookie in pro ball, home-run record holder at Div-1 college)
  • Took Full Swings prior to experiment swings (the Control group), so they could compare to when the lower half was restricted
  • Backspin Tee used on all swings (I know, shocker!)
  • Chair used to hit ball while falling
  • Pocket Radar to measure BES
  • Used 2 judges for checks and balances
  • Goal was to eliminate use of lower half
  • Every one used the same metal bat, a Copperhead C405 34 inch, 30 ounce (-4)

 

Data Collected

Based on control swings, this graph shows average BES as % of the control swings, Highest BES as %, & Lowest BES as % of each of the four hitters. Photo courtesy: BackSpinTee.com

 

Graph shows top BES per hitter on control swings, when Stationary No Hips, when Jump Float No Hips, Falling Float No Hips, Lead Leg Only No Hips, and Avg. BES. Photo courtesy: BackSpinTee.com

 

Data Analysis & Conclusion

Small sample sizes can cause a lot of problems, so there definitely needs to be more data points to make a conclusive decision.  However, with the data we have, the fact four different hitters participated on all swing experiments, in looking at the last graph, you can see that when the lower half was restricted, Ball Exit Speeds were around two-thirds of top exit velocity of control swings (normal swings).  Think Jeter making his jump throw!  So from this small sample size, we can say the pelvis contributes about one-third to the Exit Speeds of these four hitters.

I’d love to hear your thoughts in the Comments section below.  Be nice, be respectful.

Little Known Way To Optimize Bat & Ball Exit Speeds By Rotating “Under Load” (not what you think)

In today’s video, you’ll learn how to fix your flat feet

…(insert record scratch sound effect)…

“Wait a cotton pickin’ minute, so you’re showing me a video on how to correct ‘flat feet’?!  How is this suppose to help my hitters?”

…Someone somewhere might be saying 😉

The above video will be a game changer for the progress of your hitters.  It may even improve bat and ball exit speeds over time.  It may even fix some of the hitting faults you’re having a challenge correcting right now.  The content in the above video will improve both the rotational effectiveness and efficiency of your hitters.

Strength & Conditioning Coach Naudi Aguilar understands and applies Thomas Myers’s springy fascia principles in Anatomy Trains, and that’s WHY I follow him.  I highly recommend you CLICK HERE and “Subscribe” to his YouTube channel FunctionalPatterns and look into the courses on his website.  He already has  183,942 YouTube subscribers!

He’s a locomotion expert, and by the way – he talks really fast!  Here are a couple notes I took while watching the above video:

  1. Naudi talks about how the body doesn’t need lower leg to sprint at the highest level. Don’t believe me, CLICK HERE to watch this video of South African sprinter Oscar Pistorious who won 3 Gold Medals in the 2008 Beijing Olympic Games (about 0:45 minute mark).
  2. Relationship between pecs, lats, and glutes – anterior and posterior oblique slings, highly neglected part of training and carries a bigger influence on efficient movement (about 1:45 minute mark).
  3. Leg and knee should land as close to neutral as possible when running or walking with effective rotation.  If deviation occurs, then most likely there’s a deficiency in either the anterior and/or posterior oblique slings (about 3:05 mark).
  4. The idea of rotating “under load”. Using feedback mechanism – the resistance band – to “feed the mistake”.  Click to get WODFitters Pull Up Assist Bands on Amazon. (about the 4:45 mark).
  5. Practice functional movement patterns, walking, running, or hitting while using the feedback bands (about 8:30 mark).

 

In Application…

About point #1 above, as most of you know, I’ve been promoting a spine driven swing for the past 4+ years.  If you read Dr. Serge Gracovetsky’s book The Spinal Engine and Thomas Myers’s Anatomy Trains, then you’ll discover that the legs aren’t necessary for locomotion, they’re an enhancement.  CLICK HERE for a post on this titled, “The Swing Does Not Start From The Ground And Move Up?”

About points #2 & #3 above, some experts call this the “Serape Effect”, “Power Slings”, or Thomas Myers labels these a combination of Spiral, Functional, and Lateral fascia lines.  Hitters, both young men and women, will have a deficiency here. Since a majority of hitters DO NOT take the same amount of swings and throws from the opposite side, there will be an imbalance created that MUST be addressed.  Diversifying in other sports does help, but most likely, there MUST be correction.

About point #4 above, Naudi Aguilar uses a band that’s much longer than the one I use at home, so you may not need to wind it around the mid-section as much as he does in the above video.  For me (I’m a right handed hitter/thrower), to correct dysfunction in rotational locomotion, I wrap my band over my left shoulder, then around my middle back, and then loop the end around my left leg.  You’d do the reverse to enhance rotation for a lefty.  I put this on at least 5 days per week, and wear it for about an hour while doing my morning routine.  I’ve found the tightness in my right foot, Achilles, and inside part of my right knee almost vanished within 3-4 weeks of doing this.

Also, CLICK HERE to learn where I talk a little more about “feeding the mistake” using Reactive Neuromuscular Training, or RNT to correct ‘stepping in the bucket’.

About point #5 above, Naudi mentions rotating “under load”.  Coaches, I’d advise having hitters experiment using the feedback bands while hitting, and recommend they wear it at home too, as a recovery tool.

These bands are a great way to counter-balance the imbalanced movements baseball and softball inherently promote.  If your hitters move better, they’re perform better.  Swinging smarter by moving better.

David Weck & the WeckMethod are Turning Rotational Power Training on its Head

 

David Weck: WeckMethod RMT Club

You asked for it!

I had quite a few of my readers ask me about the WeckMethod of training by David Weck.  Btw, David is the inventor of the Bosu Ball, for those that train athletes for a living.  And the readers who kept bringing up his training referred to his new product the RMT Club (CLICK HERE to get it on Amazon), which you’ll learn more about in the above interview.

If you’ve never heard about the WeckMethod of training, and want to know what sets it apart, please CLICK HERE to view the following 35-min video.

If you’re short on time, then here’s a brief introduction to the WeckMethod of training from David Weck:

“What I do is more fundamental foundational work than specific hitting instruction.  My focus is improving systemic strength and power concentrating on Tensional Balance and Rotational Power – as well as non-dominant side training to provide a stronger foundation for sport specific skill.”

I feel like he’s onto something that most trainers ARE NOT. And it’s because he understands the foundation of locomotion.  He has a fantastic understanding of the human movement “rules”.

In my research, I fell into the following David Weck Carpool Tunnel fix video that helped get rid of the pinching in my right wrist, at the bottom of a push-up position, in about a week (I haven’t been good lately with my gymnastics wrist stretches 🙁:

Another great article I ran into in my research – and posted to social media – was an interview that Chris Holder did at BreakingMuscle.com with David Weck titled, “The Key To Speed Is In Your Spine”  There are great nuggets in there along with a few training videos.  It’s definitely worth your time.

The main video above is a Skype interview I did with David Weck that’s about 45-minutes.  A lot of great information in there that translates to hitters and HOW TO train power.  What follows are some of those talking points…

The Show Notes

  • How would you explain to a complete stranger what it is that you do? (1-min, 22-seconds)
  • DW explains Tensional Balance – relationship between suspension and transmission throughout your body, requires perfect alignment of skeleton, muscles, and connective tissue (1-min, 48-secs)
  •  When tensional balance & rotational power are dialed in, you can express more speed, control, power, etc. with LESS wear and tear on the body (3-mins, 10-secs)
  • Where did DW’s passionate curiosity into this realm of training come from? (4-mins, 20-secs)
  • DW discovered slow motion analysis while playing D3 college football – you cannot understand human movement with that slow frame by frame motion analysis, the eye in the sky does not lie…clock doesn’t lie…measuring tape doesn’t lie (6-mins, 0-secs)
  • Unmatched degree of intensity to enhancing human locomotion because of Bosu Ball success…was able to devote entire focus to seeking and finding answers. (7-mins, 23-secs)
  • Deep appreciate that locomotion is the key, developing straight ahead speed, is the key to developing the greatest rotational power (9-mins, 0-secs)
  • Human movement industry is about to be flipped on its head because of this breakthrough understand of “core” strength…the “Bracing Core” (weight room and picking up heavy objects) versus the “Coiling Core” (engaging in lateral movement – side bending and head over foot) (9-mins, 40-secs)
  • Real versus Feel coaching, “My athletes are doing something that I’m not coaching them to do”, high level athletes have an innate sense of speed and power, but coaches are trying to coach it out of them, elite athletes (like Olympic Gold Medal winning sprinter Michael Johnson) saying to do the exact opposite of what they’re doing on film!  Experts are teaching on a faulty foundation (11-mins, 40-secs)
  • DW is meeting with Marlon Byrd on getting specific with the WeckMethod exercises (14-mins, 7-secs)
  • Quick movement experiment…stand up right now and going through a throwing motion WITHOUT any side bending…how did that feel? Without side bend you’ll destroy your spine. You can train side bend. Locomotion is your foundation. (17-mins, 50-secs)
  • DW responds to the reader comment, “Is it logical to say that average kids can perform at a tier-1 level?” In context, the reader comment was to the claim that my 100-lb hitters consistently driving the ball 300-feet are standouts athletically.  Also, what makes a kid athletic? (20-mins, 10-secs)
  • DW explains how to train ipsilaterally (right shoulder-right hip) to get the “Serape Effect” or I like to call the “Springy X Pattern” (right shoulder-left hip) optimized for performance. Tighten the coil, time the sequence, and keep center of gravity to be neutral. Take clunky and make them fluid. (22-mins, 20-secs)
  • DW discusses the curse of moving the center of gravity during rotation.  Learning the axis of rotation, front/back, and side. Central control. Create a late rotate, like a whip. (25-mins, 0-secs)
  • The evolution of the spine, side bending is crucial to an S-shaped spine curve. (27-mins, 30-secs)
  • DW responds to the question, “Does sprinting, throwing, hitting start from the ground up?  Why or why not”. CLICK HERE for the HPL link I referred to in the video (33-mins, 30-secs)
  • DW talks about harmonizing the muscles with the connective tissue.  Least muscular contraction compared to the connective tissue. Muscles that are bound up, cannot relax.  Transmission of force, power equals speed.  Muscle acts like a circuit breaker. (34-mins, 0-secs)
  • DW discusses having tensional integrity between the muscles on the inside, and fascia on the outside. How integrity and connected the fascia is to muscles.  Bonds never lost body-weight transmission when he bulked up.  Strong is great, but not at a sacrifice of speed.  (37-mins, 0-secs)
  • We discuss Thomas Myers, Anatomy Trains, “finger flick” test to demonstrate the power of connective tissue over muscle contraction (38-mins, 44-secs)
  • DW responds to the question, “If you were going to prescribe 2 of your top RMT Club exercises to a baseball or softball player, what would they be?” Coiling Head Over Foot movement. Pulse of power. (39-mins, 30-secs)
  • DW top gifted books: Thomas Myers book Anatomy Trains, Jim Piersall book Fear Strikes Out: The Jim Piersall Story (44-mins, 0-secs)

Now Your Hitters Can Have Power Without Starting The Kinetic Chain At The Feet


I briefly viewed a hitting instructional video on YouTube the other day that one of my readers sent me (Thanks Joe),

…I won’t share who did the video, so as not to cause any embarrassment.

Like what was being illustrated in the video, I would say a majority of hitting instructors both online and off swear that the swing starts from the ground up.

This IS NOT what the current research shows as validated by human movement science.

Yes, Gravitational and Gravitational Reaction Forces do have their place (and we’ll get to that)…my point is, ALL human movement DOES NOT start from the ground, and work it’s way up the Kinetic Chain.

Consider this Tweet from one of my readers…

And I added the following comment…

What I have for you above, is a snippet of video about 5-minutes long, explaining where the swing starts as explained by Dr. Serge Gracovetsky, Physicist, Electrical Engineer, and founder of The Spinal Engine.

Here are some talking points that Dr. Gracovetsky mentions in the video (please WATCH video at the 2:00 minute mark to about the 7:00 minute mark):

  • There’s a lack of agreement in literature at what the function of the spine is.
  • Spine is generally believed to be a supporting column linking shoulders to pelvis…as we walk the trunk is thought to be carried passively by the legs.  Problem with this: WHY is shape of spine in form of an “S” instead of being straight? – straight column would support compressive loads better than a curved one right?
  • Consider 20-year-old male subject who has reduced arms and no legs…moves on his Ischium.
  • If it was true that legs are necessary for human locomotion, then a person with such an anatomy would not be able to walk.
  • With the bottom of the screen hidden [while the subject “walks” across the floor], it is impossible to tell that this man has no legs.
  • Locomotion was first achieved by movement of the spine, and the legs came after as an improvement, not a substitute.
  • When providing a lateral bend to a curved spine (lordosis), an axial torque is induced. The rotation of the pelvis and shoulders is driven by the spine.

And this is the basis for my The Catapult Loading System book on sale at Amazon.

So does the swing, or any human movement for that matter, start from the ground up?  In other words, are Gravitational Forces a necessity to move the Spinal Engine or merely an enhancement?

In an email conversation I had with Dr. Serge Gracovetsky a few years back, he said this about the relationship between gravity and spine engine mechanics:

The coupled motion has nothing to do with gravity. It works in space as well. It is a property of the spine or any flexible rod for that matter.  But the interaction with gravity makes interesting results which are exploited by every sport.”

Okay, since we’ve determined human movement DOES NOT start from the ground and go up the Kinetic Chain, I want to share a couple snippets from Dr. Gracovetsky about what role Gravitational Forces do play in dynamic movement…

Here’s a note about the importance of the heel strike in locomotion from Dr. Serge Gracovetsky in his book, The Spinal Engine (p. 168):

“…the compressive pulse generated at heel-strike is essential to the locomotion process.  The shape of this pulse must be very specific if maximum energy is to be transferred from the earth’s gravitational field to the rotating pelvis.”

According to Dr. Gracovetsky, while running, our heel hits the ground creating a compressive force that is equaled to NINE-times our body weight.  Gravity pulls our body down, and at heel strike, the ground pushes back in a compressive force.

This is why it has been demonstrated by Speed Coach Barry Ross that runners who dead-lift heavy weights with a low time under tension, get faster!  They’re able to push into the ground with more force, which in turn, the ground pushes back with equal and opposite force.

It’s also worth noting about the Spinal Engine while walking on sand versus solid ground…

Dr. Serge Gracovetsky offers this example in his book (pgs. 168-169),

“Running or walking on soft sand is not easy and is very tiring,  In this particular case, the energy leaks into the sand, the impact force is reduced, and the compressive pulse through the spine is attenuated [disabled] as the total energy recovered is reduced.”

The compressive force is softened by the sand, which doesn’t allow the pelvis to turn using efficient spine engine mechanics.  To maneuver, the brain has to recruit big muscles to do the work.  This is why you get a workout walking on sand…it’s powerless effort, rather than effortless power.

Does current research, that’s validated by science, say human movement starts from the ground, and travel up the Kinetic Chain?

No.

The trunk isn’t just a passive structure that is carried by the legs.  Legs are not a necessity to human movement – evidenced by the legless subject in the video – they’re an enhancement.  The Spinal Engine can work in space!  I say the legs and arms amplify the movement of the Spinal Engine.

Do Gravitational Forces play a role in human movement?

Yes!

Like Dr. Gracovetsky says, “…the interaction with gravity makes interesting results which are exploited by every sport.”

That my friends is a human movement principle that is validated by science.  Not philosophy or theory.  This is why my new book The Catapult Loading System is so powerful to hundreds of coaches and tens of thousands of hitters across the US… (just check the reviews 😉
