(1) The muscles of the arms should not be involved in accelerating the hands (or knob) -- the hands are accelerated around the swing plane by the rotation of the shoulders.

Video analysis shows that both of these hitters were using their arms to advance their hands (and knob) forward while accelerating the bat-head rearward during the Pre-Launch Torque (PLT – prior to initiating shoulder rotation) phase of the swing. Advancing the hands ahead of shoulder rotation causes the rotation of the bat-head to be out of sync (disconnected) with shoulder rotation and greatly limited their bat speed production.

Very interesting Jack. I can really comprehend this. I have a good understanding for all of this but I just can't get my body to do it. I know it takes a lot of practice done CORRECTLY to achieve results. What are some drills that you think really ingrain this into muscle memory?? I have your DVD so if you feel that it is on the DVD and want to discuss in e-mail I would be glad to.
