Facing shoulder height cable pulley, grasp stirrup cable attachment with one hand, palm orientated down. Step back and turn body inward about 30° to 45° to face extended arm about. Stand back just enough to allow arm to be fully extended with weight raised up slightly.
Pull stirrup back with elbow up at shoulder height until elbow travels just behind shoulder. Keep upper arm horizontal, perpendicular to trunk. Return until arm is fully extended. Repeat.
The relatively powerful Latissimus Dorsi becomes involved:
- if upper arm travels closer than perpendicular to trunk
- if torso is positioned forward beyond vertical
- Teres Minor
- Deltoid, Lateral
- Trapezius, Middle
- Trapezius, Lower
