Purpose of Exercise: To work the rear head of the deltoids. By using cables, you get a slightly longer range of motion with continuous resistance throughout the movement.
Using two floor level pulleys, take a handle in each hand with your arm crossed in front of your body (left hand holding right cable and right hand holding left cable. Keeping your back straight, bend over until your torso is about parallel to the floor. With a smooth pull, and arms nearly straight, draw the handles across your body and extend your arms straight out to either side, turning your wrists slightly, thumbs down, as if pouring a pitcher of water. Stretch as far as possible, then release and let your arms come back slowly across your body as far as they can.
