>>> You all keep talking about tht as if you think you know what it is. But I defy 5 different people to briefly define YOUR definition of tht, and I am willing to bet you will get 5 different answers.Sure, you can cop out by saying "reaearch the site" or "buy the dvd", but can ANYONE really articulate what tht means to them? I DON'T THINK SO! <<<

I will give you as quick and concise definition as I possibly can. -- During initiation, THT applies a force at the handle that assists shoulder rotation in accelerating the bat-head in the swing plane (back toward the catcher). --- Hitters like Bonds, Sosa and etc., use THT during pre-launch (before shoulder rotation and the lowering of the elbow to the slot). The acceleration of the bat-head is supplied from the pulling back of the top-hand by the adduction of the arm and shoulder complex (no shoulder rotation involved).

Because I've been applying THT simulatneously with my hip rotation, and I seem to be dropping the back shoulder and hitting pop-ups. any solution?

> I dont understand why everyone has such a difficult time understanding top hand torque. If you understand what torque is and you look at a clip of Sosa and think "well let me see if I can find the top hand applying torque to the bat" it is very clear. Sammy does start applying top hand torque before he initiates shoulder rotation as can be seen in numerous clips. It is the same for Bonds too. I like the clip of Bonds from behind his back shoulder that shows his hands from the Youth Baseball Coaching site the best. It shows all the pre-launch movements and THT along with Bonds' perfect CHP and "hook" in the hand path.

> grc- how is it not a direct source of power? If you are using your top hand and forearm muscles to accelerate the bat then you are clearly generating a direct source of batspeed (assuming you believe batspeed allows a person to hit for power).

> I sent Jack my tape for review and he mentioned to me that I wasn't applying Top Hand Torque and my bat was not in motion before shoulder rotation. He showed me a clip of Sammy in the home run derby and described what it is and it became very simple and easy to understand. I worked hard and started to apply top hand torque before shoulder rotation and hit my first home run of my life (oppo) this year and also hit a ball over 300ft with wood off of a change up. Not bad for weighing 145 at the time. I of course still havn't perfected it but I know its there from video clips and the jump in power.

dave, in answer to your question of why tht is not a "direct source of power".....per jack, "THT applies a force at the handle that assists shoulder rotation in accelerating the bat-head in the swing plane (back toward the catcher). --- "......the key word is "accelerating"....the bat is not "accelerating" at this stage of the swing, it is MOVING....slow, but moving, a POSITIONING movement....there is no more power gained from the "accelerating" movement than there is from any power gained by the forward movement of the stride....

the swing and acceleration of the bat starts at or shortly before front heel plant, and anything happening prior to that (including the knob tp the pitcher thing) is simply positioning movements as well as some inertia-busting movements.....
