A problem that some of my hitters are having is that when they load they seem to be turning their whole upper body in as they stride and I can see their head being strained or turning in slightly causing vision problems.I have had them hit with no shirts on and it appears that they never get actually loaded properly[no pinch in rear scap] though they have rotated in alot and moved their hands back.This is being counter productive not only in the load but also their vision.Has anyone seen this or have thoughts
