Set the cable pulley around shoulder height and attach it to your Arm Anchor. Stand facing away from the machine with your working elbow raised out to the side at shoulder height and bent at 90 degrees, with your forearm upright. Rotate your shoulder to bring your hand forward and downward until your forearm is level with the floor. Slowly return to the starting position. Keep your upper arm steady, your wrist neutral, and your torso upright throughout the movement.
