Step-over move to activate aggressive hip rotation


#1

Does anyone here teach the step-over move to activate an aggressive hip rotation? I would be interested to hear people’s thoughts on this maneuver, as I’ve seen some people claim it is used by many hard throwers…Is it something they are actively working on, or a byproduct of other factors?

To be more exact in my explanation…It appears as if the pitcher is striding sideways leading with his heel/outside of his foot towards home and then picks up and kicks over into foot plant.
