RE: Rushing The Shot Problem
what your friend has is target panic, he is snap shooting. The best thing he could do is shoot at a blank bail from 5 ft. away with his eyes closed so he gets the feel for a proper release again. This will help him re-teach is subconcious that he can hold on target while aiming in stead of feeling that he has to release the second he is on target. Also just holding on target and letting down without releasing the arrow would be a great tool to use as well. Good luck.
