Sit slightly forward on seat or bench and grasp ends of rope attachment with hand. Place feet on vertical platform. Slide hips back so knees are slightly bent.
With torso upright pull rope upward over head until elbows are approximately lateral to each ear. Lower stirrups forward and downward until arms are extended straight in front of body. Repeat.
Keep torso upright while maintaining fixed slightly bent elbow position throughout exercise. Stirrup is raised by combining shoulder abduction and flexion with slight external rotation. Also see Cable Seated Y Raise on dual pulley machine with stirrup attachments.
