If I’m not mistaken from what I was taught in college and the minors…is that a pitcher’s leg and hip power during pitching comes from when the stride foot lands[/quote]
Agreed. Good tempo down the hill to build up some momentum followed by a strong front leg abruptly putting on the brakes after the front foot plants should result in more explosive hip rotation.
I’d be careful about trying to teach a back leg push. Initially, there is a sideways push with the hip abductor to initiate movment towards the target. And there may be some plantar flexion right before the back foot turns over. But at, or slightly before, front foot plant, the back foot does turn over to allow the hips to fully rotate and there is not pushing going on at that point.
