What turned you into a kinetic link man???Physics??????Crack the whip baby!!!!!!
Hi Chris -
Been drinking a lot of coffee this morning?
The kinetic chain is how the body gets it done. But I look at the picture (upper left) and don't see a closed/rigid front side. I see a flexed front side, hips already starting to open and getting ready to open more as the front leg torques the front hip back (at the same time the back leg turns over and torques the back hip forward) : both hips turning around the stationary axis of the spine!!!
( and all that AFTER weight shift (notice the trailing shadow figures))
