Re: Rich: Some Thoughts

> > > Please remember that the rotational swing is a "ground-up" mechanic. In order to apply optimum force to the bat, the gyrating front leg must rotate the front side of the torso, whereas the gyrating back leg must rotate the back side of the torso. This, in turn, will rotate the shoulders, and arms. The rotating arms, in turn, will spin both hands around each other, and provide power initiated through the kinetic chain by their corresponding foot / leg. These forces cause the bat to arc around the body.

Remember, that swings that arc 90 degrees (i.e., towards the pitcher) have less time to accumulate optimum force than swings that arc 180 degrees (i.e., starting to arc back towards the catcher, then arcing towards the pitcher).

During my formal trainer as a researcher, one professor suggested that, whenever elaboration is needed, but the added information is likely to muddle the concept presented, an endnote is needed.

Hey BHL,

You've mistaken me for someone else on the getting out of the chair cue. Mark H. loves that cue... i tend to disagree with it.

The waist is bent at heel drop and at contact there is a straight line from the foot thru the shoulder.... HOW? they must raise up, right?
some do a couple of inches as can be seen in the upward movement of the head. i don't like the head moving. the less the better in my humble opinion. steady head = steady eyes = more focus on the ball... less variable information going to the subconscious for computation of where the ball will be at contact.

I think the head can remain steady as the hips are rotated AND thrust forward/upward under the stationary head. the rotation and thrust are very powerful movements that enhance each other thru the push of the rear leg and the straightening of the front leg.

If we teach "get up" that might be a little misleading in my opinion. it's a much more difficult movement. like THT, it's something i don't talk about to the young hitters. Here's what they need.
1) full hip rotation
2) torso connection to full hip rotation
3) shoulder connection to torso rotation
4) full shoulder rotation, no slowing
5) front arm connected to shoulder rotation(no slop)
6) bat in the same plane as the front upper arm at launch
7) bat still on the same plane as upper arm at contact(NO WRIST BIND)

Those are the MAGNIFICENT SEVEN... if i get my students there i'm a happy camper. then and only then will i start looking for the small stuff ie., front elbow up, bat lag in good position, back elbow staying close to slot, hands at launch, hands still at launch position half way into shoulder rotation, etc.

I just realized that i forgot one... so it's the MAGNIFICENT EIGHT!!!!
and #8 is, or it actually is #1 in my book STATIONARY HEAD AFTER LAUNCH.

I'd be very interested in what's the most important teaches in your estimation... and all other good people on this board.

Best regards, Rich
