Lying Rotator Cuff Exercise
A precise corrective movement designed to stabilize the shoulder joint and improve long-term overhead health.
How to perform.
Follow the sequence — setup is half the lift.
Lie on your side on a flat bench or a comfortable mat with your legs stacked and hips neutral.
Rest your head on your bottom arm and tuck a small towel roll between the elbow of your top arm and your ribcage.
Grip a light dumbbell in your top hand and bend that elbow to a ninety-degree angle so your forearm rests across your stomach.
Slowly rotate your forearm upward toward the ceiling while keeping your elbow pinned firmly against the towel and your side.
Stop the movement once your forearm is perpendicular to the floor or as far as your mobility comfortably allows.
Lower the weight back to the starting position with a controlled tempo to maintain tension throughout the rotator cuff.
Complete the desired number of repetitions before switching sides to repeat the process.
Common mistakes.
Fix these first — they cost reps, kilos, and joints.
- Using momentum or swinging the weight instead of using a controlled rotation.
- Lifting the elbow away from the torso which shifts the load to the lateral deltoid.
- Rolling the entire torso backward to help lift the weight rather than isolating the shoulder joint.
Muscles worked.
The primary movers do the work; the stabilizers keep the path honest.
