Bat Path

[DRDRODD]

Barry's bat doesn't move until he can push against his legs and create rotation. His "hand" torque moves the bat so fast that he would never get the bat on plane or to the ball if he wasn't into his legs and able to create fast rotation.
@julray knows that Barry's "hit the ball on the plate" drill is strictly a hands demo with no legs or spine tilt......It's strictly a bat torque drill.

Are you saying the upper can’t rotate until the legs are on the ground?

Are you familiar with Fascial lines?

The RHE is due to limitation in range of motion. Why does a hitter put pressure on the instep of the back leg? How far can the rear hip extend the leg rearward? At some point the leg can't extend rearward any more. It is literally attached at the hip!
Same for the front leg. It gets extended, pushing the pelvis rearward and at some point can't extend any more. ROM.
The pelvis is turned by the extension of both legs.
As the pelvis is turned, the legs reach their limit of ROM and no more rotation is possible.
The pelvis isn't being moved away from the rear leg, it is being moved by the rear leg via hip extension. The very word extension tells it all.
The rear leg gets dragged forward by pelvic rotation because the front leg still has ROM after the rear leg reaches it's limit.

WW's daughter has a pretty swing, but she doesn't use her legs much so there's no power. She swings as though someone told her "Do not use your legs. They will cause problems in your swing." I wonder who might have done that?

The bat rotates because the rear hand is used as a fulcrum against which the front arm applies leverage to the bat. The ONLY way rotation happens because of torque. There is no other mechanism to create rotation. NONE!
The barrel doesn't come over the top because the rear hand fulcrum is applying downward resistance to the upward pull of the front arm.
Centrifugal force is a result, not an action. The barrel rotates down because of the upward force created by the front arm, offset from the center of mass of the bat and because of the fulcrum of the back hand.

no offense taken Bobby. But the legs in the swing are used for stability. So the pelvis can extend reactively in a small window. Something to leverage against. That’s the last bit of oomph that is needed. I am not saying her swing is perfect. But it’s pretty good power wise. Here’s another gif of her swing. Try to understand cross body contractions.



see the legs both snap forward? The hips are doing that against the legs. See how the back foot gets pulled back down? She doesn’t leak forward. Cross contractions which originate from the middle or reciprocal movement powers the swing. From rear shoulder to front hip, back to lead shoulder to back hip. The legs are for stability and the feet are the anchors.

More correctly, the core muscles and obliques can only contract and move one level or corner toward the other.... ie....top to bottom..... crunches....or left shoulder toward right hip and vice versa... diagonal crunches(?)
The obliques cannot forward rotate the pelvis without the shoulders being anchored to some outside anchor point.
Actually, since muscles only contract, they all rely on outside anchor points to create locomotion. Otherwise they're moving one body part relative to another body part and not actually moving in space.
Since we connect ourselves to the ground via standing, all the upper body parts (distal to the anchor point) leverage off of the lower body parts (proximal)

Nice post W=W........ the back leg acts as an anchor to create tension (the brakes). One side is compressing as the other is getting lengthened, creating compression and tension across the body.

Imo, the legs provide the force.
Also, arguing with you is a waste of time.
If you want to prove the point, have her sit in a chair, feet off the ground, and use those obliques...... remember to anchor her to the chair.... the legs are mere anchor points and don't power the swing. She should be able to hit as far as she normally does. The legs are only for support and the chair should do just as good.
Otherwise, you are wasting your time because I require visual or scientific proof.
I'll never take your word.

Sit in a chair, feet up.
I want to see your pelvis move in the seat due to oblique contraction.
Create tension and swing the bat.
Let's see how far you hit it without the legs providing power.
PLEASE PROVE ME WRONG!
Can't do it.

Sit on a swivel stool and swing the bat and hit a ball.
Get the ball flight in the video.
Show me the obliques power the swing through reciprocal motion.
Somebody????? ANYBODY??????

I have never posted anything about the oblique’s. I am referring to it more as a whole, which is why I refer to it as the middle. If I had to put a name on it, it would be the spinal engine.

I don’t believe anyone is saying the feet or the legs aren’t needed........ there has to be anchors involved.

Did you have scientific evidence when you learned tTB ?? hopefully you stick around. Someone around here will come up with it eventually. Have a good day Bobby !

Now it's the spinal engine....Arghhh!
Spinal engine ain't legs.
Are you saying the legs power the swing or are they merely anchors?

1) Do the legs actively power the swing?
2) Are the legs the main source of the power in the swing or is something else responsible?
