similar but not the same

That clip was shown here in the past. He danced around that clip and never really explained it. How can u push/block/push with one leg? He used scientific words if I remember correctly. Still didnt explain it layman terms for dads and their dd's.

OK, I'll make it simple. The one-legged guy rotates, just like every MLB hitter rotates except that most MLB guys have two legs to use to get max rotation.

I didn't dance around anything, you just can't comprehend the science.

It is what a coach would call a "short" swing. Not 1.Push 2.Block 3.Push back and swing. It is internally rotating rear leg and hip WITH swing INTO a block. When the swing is part of power move, and not 3 moves to create power then swing, a hitter can "sit back" longer before committing fully, helping with the off speed. When a hitter is late...the swing is part of the first motions...a hitter can catch up quicker.

You don't push block push and THEN swing. The PBP is part of the swing. The lower half force generator.

No wonder you don't think it's right. You still don't get how it works. If you taught your DD to PBP and then swing, no wonder you didn't like the results.

In short, simple terms, the following are APPROXIMATE timing of the sequence; the hands prepare to throw the barrel during the push, they connect during the block, and the throw starts during the push back.

Again, APPROXIMATIONS;

Pujols does the Push from about frame 16 to 18, the Block is about 18 to 21, and the push back is about 21 to 24.

His hands and barrel are active during the block. He doesn't shift THEN swing, but he DOES, push-block-push.

I don't sell any DVD's, nor do I get a cut of anyone else's, nor do I get paid by anyone other than my students.

You simply do not understand the physics of the swing. I can't help that. But, your ignorance is not a valid reason to start bashing what I state. You don't understand that push-block-push is not a technique it is a layman term to describe the very basic bio-mechanics that create the physics in the swing. You can coil as you now believe, and execute the swing from a coiled position and hold the coil if you think you should, but you will still push to get going, block that momentum, and push back to cause rotation. It's a fact that you seem unable to comprehend.

Geez, once again, I try to focus on a point, and you miss it completely.

I was speaking of rotation of the torso in general terms. The lower half (hips) turn before the upper (shoulders). Hip rotation is happening during the push and block, but the upper half goes during the block. The push back finishes the rotation of the torso. When I said causes rotation, I should have said that it finishes the rotation.

Let me quote your guru word for word and you tell me at what point I mis-understood.

"1st the back leg drives the rear pelvic bone forward. Then the front foot lands. Then the front leg finishes by driving the pelvis open from the front and the pelvis pulls the upper body into rotation."

Some motions that are added to a swing, make it more efficient, thats all. When both legs work together thats as good as it can get. (i know, along with scrunch etc)

Try to do what this guy is doing.

You will see that you can't swing with your arms and upper body. You will feel the tightness in the lower back. You will feel the leg and rear hip as the driver.


So, could it be that there is no push block push? Could it be that the front side is just playing catch? That the rear side is transferring the energy? That the what some believe as the push back to straighten the front leg is really not a push back but rather a snap back? In other words the rear hip is moving forward and because of that the front hip is moving the opposite direction, which makes it move away from the front foot, straightening the front leg without a push?

Now, I am not saying the front leg does not play a role. I am saying that it doesn't produce energy from a push back. There simply isn't enough time to do all of that. Unless I start really early and guess a lot. The energy has to be able to be delayed and instantaneous. One leg.

That is why, again, I would like for a physics guy to use their physics to explain a MLB high level swing and any of the 8 year old girls on this forum. Then I would like for them to explain the physics of the one legged golfer.

You can perform an over-the-top arm powered swing from one leg .... it's just that from one leg it feels very 'wrong'.

stretch and fire/spine engine/sequential loading and firing of muscle stretch receptor reflexes [SSR] is a much better way to understand the high level MLB pattern (than the muscular force production sequential arc of traditional kinetic chain model) which is the same in Ichiro (whether he is hitting long ball or not) and Ruth. The spine engine model emphasizes the important elastic energy aspect of mechanics which is necessary for quickness and adjustability including efficient momentum transfer. The body is moved/wound up to make this mechanical action possible as spatially far back/"early" as possible.

Tom ... well stated IMO.

Jim ... just want to give a somewhat different and complimentary perspective.

You are speaking of the synchronization relative to the use of two legs.

While it is true that most of us have two legs, there can be value found from considering a one-legged/rear-legged view point. From a one-legged/rear-legged frame work, one can capture the value and sync of the 'back side'. That is, one can understand the importance of the spine engine ... or the scrunching action of the rear lat ... or lateral tilt, in terms of the capture of barrel transition. Make no mistake about it, it is the capture of barrel transition where many error and get lost. Capture the transition of the barrel incorrectly, and the swing is off to a rocky start ... and while every swing is in part an athletic adjustment, it is the athleticism employed after the proper capture of barrel transition that leads to highly adjustable swings.

If you perform a one-legged/rear-legged swing that is powered with your arms, then it will feel wrong and it will feel relatively weak.

On the other hand, if one learns to use their body appropriately to "turn the barrel" ... and learn to make use of the spine engine, then the very act of turning the barrel will have the hips leading ... and the critical sync of capturing barrel transition will be learned.

There is definite value in having two legs ... but there is a huge value in terms of learning to "turn the barrel" in a manner that properly captures 'barrel transition'.

Valid statements, but you're talking about acquiring a feel. Feeling a synchronization of body parts. I'm talking about kinetic energy flow, and the physics of the swing, and the bio-mechanics that create the energy flow.

Sure, you can swing from one leg; either leg, but you cannot create as much acceleration of the barrel, nor velocity at contact, as you can with two legs. And, it isn't just because of better balance.

The one-legged golfers are using their hip flexors, their obliques and spine muscles to get rotation. Two-legged hitters use the same, but they can get more momentum than the one-legged hitter, because they can apply force from more sources and in a cumulative sequence.

Can you accelerate a bicycle as well with one leg, or two?
