Well you asked! I would define weightshift as a 2 fold situation when it comes to the swing. When the stride begins the body cocks or loads allowing "The Stride to 1st transfer the weight back, Not forward" and by the way this isn't a sway and it also will vary to some degree with each different hitter, but they all do it! 2nd, after the stride occurs that weight then is transfered forward against the frontside and the hands arrive in the launch position. This is a balanced transfer. Any unbalanced transfer forward ONTO the frontside would be considered a "LUNG".

You initiated your yellow line right before rotation? Why then and not before the stride. Myself and anyone else for that matter would agree that the head and body do not continue to move forward after you have blocked the frontside, which is when rotation begins. Chris Yeager teaches the same concept? yes, no????



> >>> Jack....Does Chris Yeager believe in a swing gate swing? I have your Final Arc dvd and Chris believes and demonstrates the swing that your assistant is taking on the field while you viewing him from the side. Notice how he apply's a force with his lower half and also notice on YOUR FINAL ARC VIDEO HOW HIS HEAD IS MOVING FORWARD until he blocks his forward movement with his front leg. I have heard Chris say WHIP ACTION.....wouldn't swinging gate and revolving door be your interpretation? also, would you say the STRIDE is to transfer the WEIGHT BACK and not forward???....notice I said transfer and not SWAY. <<<

> Just before he initiated rotation, we drew a yellow line running down through his head, neck, out the butt into the ground. It showed his lead-shoulder about 8 to 10 niches in front of the line and his back-shoulder about the same distance behind it. As we advanced the frames, his head, neck and butt never moved off the line. His lead-shoulder rotated back to the line as his back-shoulder rotated forward – like a “revolving door” – not like a gate swinging on hedges.
