Set the cable pulley low and attach it to your Arm Anchor (D Ring on the back of the hand). Face the machine in a staggered stance, with your working arm extended and your palm facing forward. Bend your elbow to curl your hand toward your shoulder, keeping your palm facing up as you lift. Squeeze your biceps, then slowly lower to the starting position. Keep your upper arm close to your side and your torso upright throughout the movement.
