>>> 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. <<<

Hi Jeff

We pretty much covered the topic in our discussion above. I will just address a couple of your comments.

>> on YOUR FINAL ARC VIDEO HOW HIS HEAD IS MOVING FORWARD until he blocks his forward movement with his front leg <<

In the video we showed that John’s axis (and head) moves forward during his stride. We also showed (across the plate view) a frame-by-frame of his axis coming to a complete stop before he initiated the swing.

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.

>>> would you say the STRIDE is to transfer the WEIGHT BACK and not forward???....<<<

Jeff, it would depend on how you define “weight transfer.” Below are a couple comments I made on the topic.

“Is “weight shift” just to indicate which leg is most responsible for supporting the body’s weight at different points of the swing?”

“As I pointed out above, for a “weight shift” to occur that produces linear momentum, the center of mass (the spine) must attain velocity. So I would define “weight shift” as “forward axis movement.”

How do you define “weight transfer?”
