Dumbbell lying external shoulder rotation

How to do it

1. 1 Lie down on the floor on one side. Raise your arm holding the dumbbell from the side to shoulder height and bend your elbow to 90 degrees with your palm facing forward (starting position).
2. 2 Now move the dumbbell towards the ground by rotating your shoulder position until your forearm is parallel to the ground. Return to the starting position by rotating your shoulder in the opposite direction.

Tips

• Make sure that the angle between your shoulders and elbows is 90 degrees.
• Only rotate your shoulders and avoid doing any movement with your elbows.
