Have you considered, or is it even possible to maybe try a new coach? If my dd's PC reacted in that manner, I'd be a little perturbed. As Bill said, the PC should have no problem explaining exactly WHY each "drill" or movement is done. Fortunately, we don't have a PC like that. He explains everything to my dd, multiple times, in the hope that something sticks.... right Bill?...lol. He has dd do her warmups/drills before full motion. It takes a fair amount of time, but it is all done involving the whole body in the movement. So, even if it did nothing for her pitch itself, it also serves to warm up all the muscles that she will be using in her full motion. I would look for a coach who falls more in line with what you feel or may be learning is correct.
Crystlemc - I see your point and know where you are coming from. My dilemma is that while I might disagree with some of her isolation drills, she is really great with my DD (and other kids) especially in the manner/tone she coaches (firm, yet sweet) and has really helped DD this past year, go from no pitching experience to starter. I guess I am hoping that as DD gets better, the need for PC to teach isolated drills will be lessened? Amy - sorry for hijacking your post!
