Grasp end of Triceps Rope Cable attachment with one hand so that protruding end is in contact with side of hand (thumb and index finger). Stand away from pulley with arm back at side and elbow straight.
Raise stirrup forward and upward until arm is well above horizontal or cable makes contact with underside of upper arm. Lower and repeat. Repeat with opposite arm.
Absolute height of movement may depend on range of motion or when cable makes contact with underside of forearm. Raise should be limited to height achieved just before tightness is felt in shoulder capsule. Alternatively, height just above horizontal may be considered adequate.
