> Hip rotation starts as the hitter's coil turns to uncoil. No pause between. He's riding his back leg at that point and carrying momentum forward. There is a linear component to this momentum. But it is mostly rotational. He is not shifting weight at this point.

> The hip rotation is around the rear hip ball and socket joint. It is induced by the muscles of the rear leg and rear hip socket. I suppose the lower torso/hip muscles are involved also. The opening of the front leg also helps. It continues as a running start....not aggressive at this point......just creating momentum and creating stretch between the upper and lower halves. The front foot is still in the air for most of this. And a load is maintained in the rear hip ball and socket joint as this occurs.

> Then.....at "go".....after the hips have offset...where the hitter's provate parts can be seen by the pitcher....the hitter unloads the rear hip joint with a push against the ground and a push in and against that rear hip joint....forcing both weight shift and rotation. This forces the weight forward which is caught by the front leg which then provides a lever which firms up making sure there is no drift forward, which would bleed rotational energy from the system. The front leg is NOT a source of rotation. It is not an engine firing sending the front hip rearward. It is simply a lever that creates a pivot point for the hips to keep them from drifting forward. IN THAT SENSE....the front leg does help turn linear momentum into rotational momentum....by simply offering the lever to rotate against. It does not act as an engine of rotation.

mr. teach!
a beautiful day!! something we are in agreement about!!somewhar..
i would have to disagree about what the front foot is doing..
you are making WAY too much of the breakdown of the front foot action
in your world you would make a 2-step sequential operation of the
feet touching down & firing... back foot first & the front foot AFTER, & then using a lot of confusing words to describe the functi
on of the front leg as a "LEVER"... A LEVER HAS TO HAVE A FULCRUM TO USE AS A BASE TO PUSHH OFF OF... so here are my questions:
1. where is this fulcrum the lever (leg) is pushing off of?.. in other words, what is levered against what? i don't see it.
2. what is the function of this "levering action?"

here is where you lose me:
"This forces the weight forward which is caught by the front leg which then provides a lever which firms up making sure there is no drift forward, which would bleed rotational energy from the system. The front leg is NOT a source of rotation. It is not an engine firing sending the front hip rearward. It is simply a lever that creates a pivot point for the hips to keep them from drifting forward "
1. levers do not "firm up".. you're merely incorrectly describing the touchdown & braking action of the front foot..
2. almost instantaneously as the front foot touches down, BOTH FEET SHOULD BEGIN CORKSCREWING IN UNISON!!! THIS IS HOW YOU GENERATE LOWER BODY TORQUE.. implementing BOTH feet in A ROTATIONAL ACTION WILL ACCENTUATE THE TORQUEING OF THE HIPS... IN UNISON!! you cannot eliminate or diminish the rotational action of EITHER FOOT.. TO DO SO WILL DIMINISH YOUR LOWER BODY TORQUE.. how in the world can anyone say that half of the base is not to be utilized in generating lower body torque?!?! to do so will partially diminish the lower body torque, thus diminishing your resulting batspeed...
WHEN GENERATING LOWER BODY TORQUE, YOU CANNOT ELIMINATE OR DENY THE USE OF EVERY PART OF YOUR BODY, INCLUDING THE LEAD FOOT.. YOU MUST UTILIZE EVER PART OF YOUR BODY TO ITS MAXIMUM ABILITY IN ORDER TO TO GENERATE THE MAXIMUM BODY TORQUE, THUS MAXIMIZING BATSPEED... to do otherwise will invariably result in a diminishing of the batspeed generated... not a good thing. so,

FACT: THE FRONT FOOT IS A SOURCE OF ROTATION!! IN FACT 2 SENTENCES AFTER YOU SAY IT IS NOT A SROUCE OF ROTATION, YOU MAKE A STATEMENT WHICH IS IN DIRECT CONTRAVENTION:
"the front leg does help turn linear momentum into rotational momentum....by simply offering the lever to rotate against. It does not act as an engine of rotation."

this "lever to rotate against" .. hard to figure out what the heck you're trying to convey...
the fact is once the front foot touches down,it provides a braking action to forward momentum.. at that moment, you should begin to rotate BOTH feet in order to generate lower body torque.. i don't understand where the levering action is coming from., & YOUR LAST STATEMENT IS TOTALLY WRONG... THE FRONT FOOT IS NO DIFFERENT THAN THE BACK FOOT, IN THAT IT SHOULD PROVIDE THE BASE FOR GENERATING LOWER BODY TORQUE..

FACT: BOTH FEET ARE ENGINES OF ROTATION. to think you should not
consider engaging one foot in the pursuit of lower body torque is to sabotage yourself to the point of guaranteeing failure to generate maximum batspeed.... sorry.
