Abstract: A sports training device is worn by the trainee for developing skill and minimizing risk of injury in pitching, passing, swinging, kicking, and other such sports-related body movements. An illustrative embodiment includes an anchor member adapted for wear on the torso of a trainee, and elongate member coupled between the anchor member and a forearm or thigh of the trainee, the elongate member being resiliently bendable along its length, inelastic relative to its longitudinal axis, and freely movable relative to the anchor member upon movement of the trainee's arm or leg.
