This strength training exercise works on the internal rotators of the shoulders. It must be done on a training pulley. This exercise is often used as a rehabilitation exercise after an injury to the rotator cuff of the shoulder. The exercise can also be done with an elastic band. The pulley or elastic allows constant resistance during the eccentric portion of the movement.
