Where in that Video is it stating that It fires first. I think it is sound what the guy is explaining, but It doesn't say its firing first. . If anything you stretching the obliques, so that you can have maximum contraction, right?
By the way at the 32 second mark it shows the kinects starting from the ground up, do you disregard that?
Must have miss this. The way I see it is the energy gets PUT into the ground. It doesn’t start there.
