Notice that the right shoulder and right hip move back behind on a line of the right foot.... Imagine your a puppet and the puppeteer standing behind you (on line with the right foot) with 2 ropes attached to your side of your right hip and right shoulder - then pulling them back. Is this correct in your view ?
Isn't this against TGM? Seems the spine moves in and back to the right some. More of a lateral shift than what is in the book.
I use to do the left shoulder over the right foot, but it caused me to shift to the left to much in a slide dive.
