How do I perform a rotator-cuff rotation?

Either lie on your side or grip a cable with a handle directly in front of you at hip height. Keep your core engage, spine in neutral alignment and your elbow bent at 90 degrees. Start with the dumbbell or cable handle held against the body and while keeping your upper arm held against the body and the elbow bent at 90 degrees.  Rotate the arm away from the body approximately 90 degrees and then return to the starting point. It’s very important to keep the elbow bent and the upper arm close to the body at all times.

Lie on your side on a bench or on the floor with a weight in your top hand. Bend your elbow at a 90-degree angle and hold your upper arm against the side of your body with your forearm down across your body. Lift the weight by rotating the top shoulder outward while keeping your upper arm against the side of your body. Lift until your forearm is almost perpendicular to the floor.
