Shoulder External Rotation (at 90 degrees)
- HOW: Using a resistance band or another form of resistance, start with your elbow raised up to shoulder height. Rotate your hand outwards without changing your elbow position.
- FEEL: You should feel the muscles on the back of your shoulder working.
- COMPENSATION: You do not want to feel anything in the front of the shoulder/arm. If you do, you may need to regress this exercise.
