Abstract
Abstract A strap, preferably elastic, extends between the middle of a bowler's back and the upper portion of the bowler's free arm. It inhibits rearward movement of the bowling shoulder and/or rotational movement of the shoulders that could result in a follow-through angle of less than ninety degrees. The strap, which preferably is at least partially elastic, can extend between a body belt that encircles the bowler's torso at the waist and an arm belt that encircles the free arm in the biceps region.
