Re: Re: Re: New video - Shoulder rotation

Hello Jack,

Thank you for your response. I have watched the videos you referenced multiple times but I have to admit that they were not helpful to me. Any chance you could make the raw video of the full swings available?

Specifically, what is causing the rotation of the shoulders? Contraction of the large muscle groups causes contraction of the large muscle groups. How does rotation factor in?

Also, how does lead-shoulder rotation pull the bat rearward on the approach to contact? How is this not drag? Your THT term would initially create rearward action on the barrel, but pulling with the lead shoulder would in effect cancel out this action.
