What is considered foot strike when the first part of the foot hits or the whole foot plants? This pertains to timing of equal and opposite elbows for timing. Thanks .
Either is fine. Using “first contact” is probably sufficient. I normally use the cue of staying equal and opposite “as long as possible” - most pitchers won’t stay equal and opposite beyond full foot contact.
i think of it as being most of the weight is shifted to the lead leg, if not full weight… arms should be somewhat equal/opp with the throwing arm at the high cocked position
this position us just before upper body rotation and throwing arm needs to be position comfortably
