How Iridium Programs This

Iridium programs this lying variation to target the rear delts and traps while removing lower back involvement. If your 7-day workout history indicates high spinal loading, the AI prioritizes this exercise to meet upper back volume requirements without compounding systemic fatigue. This stability allows for accurate RPE tracking on small muscle groups that are otherwise prone to cheating with momentum.

Form Cues

Lie on your back under a high pulley with enough clearance for the cable to travel freely.
Use a rope or two extra-long D-handles so you can pull wide without the attachment limiting range.
Lead the pull with your elbows, driving them out and down until your upper arms reach the floor (as tolerated).
Squeeze your shoulder blades together while keeping your ribcage down.

Don't

Don't arch your lower back to help move the weight.
Don't let your elbows drop below shoulder height.
Don't jut your head forward to meet the rope.
Don't use momentum to swing the weight up.

Common Mistakes

Using too much weight
Turning the movement into a row
Lack of external rotation
Letting the elbows drift narrow instead of pulling wide

Muscles Worked

This exercise primarily targets the posterior deltoids and the rotator cuff muscles by combining scapular retraction with external rotation—key for counteracting rounded shoulders. It also engages the middle trapezius and rhomboids for upper-back strength and posture. The supine setup minimizes momentum and reduces the temptation to compensate through the lower back.
