now, i am finding my training is going MUCH better limiting my range of motion... i feel less injured (rotators) and i feel they hold me back less... i am not talking pussy bench press half way down... i mean for DB presses done to the chest, not past... DB's for shoulders to ear level.... fly exercises NOT going past my torso so i am not all stretched out... i think this keeps the tension on the muscle being worked and keeps stabalizer muscle use to a minimum, yet still working them efficiently... just not over doing it.
