Stand with side to shoulder height cable pulley. Grasp stirrup cable attachment with hand furthest from pulley. Position arm across neck with elbow bent 30° to 45° outward.
Keeping elbows pointed high, pull stirrup out to side, maintaining fixed elbow position throughout exercise. Return to original position and repeat. Repeat with other arm.
Upper arm should travel in horizontal path at shoulder height (not downward) to minimize Latissimus Dorsi involvement.
