How to Do Lying Dumbbell Internal Shoulder Rotations

  1. Lie down on your side, with your arm close to your side, and your elbow bent to 90 degrees.
  2. With a dumbbell, rotate your arm internally (upwards) against the direction of resistance, as far as possible.
  3. Reverse the movement, and repeat for reps.

Commentary

Internal rotations train your anterior rotator cuff muscles (subscapularis).

By lying on a bench, or similar elevation, you can increase the range of motion compared to lying on the floor.

Alternatives to using a dumbbell are to use a cable pulley or elastic bands (while standing up).
