How to Perform the Dumbbell External Rotation
- Lie on your side on a bench or the floor with a light dumbbell in your top hand.
- Bend your top arm to 90 degrees at the elbow and pin your elbow firmly against your side.
- Start with the dumbbell resting near your stomach with your forearm across your midsection.
- Rotate your forearm upward and away from your body while keeping your elbow pressed against your side.
- Raise the dumbbell until your forearm is roughly vertical or you feel the end of your comfortable range of motion.
- Slowly lower the dumbbell back to the starting position under control and repeat.
Common Mistakes to Avoid
Using too heavy a weight
Use a very light dumbbell (2-5 lbs to start); the rotator cuff muscles are small and easily strained.
Lifting the elbow away from the side
Keep your elbow pinned to your side throughout to isolate the external rotators.
Performing the movement too quickly
Use slow, controlled reps with a focus on feeling the rotator cuff muscles working.

Pro Tips
- ●Place a small rolled towel between your elbow and side to maintain proper spacing if needed.
