1. Lie on your side on a bench with your top arm bent 90 degrees at the elbow, forearm pointing toward the ceiling, holding a light dumbbell.
2. Keeping your elbow pinned to your side, rotate your shoulder to lower the dumbbell toward the bench in front of you.

4. Complete all reps on one side before switching.
