HOW: Stand on a band to anchor it from one end. Hold on to both ends of the band with your hands, then raise your arms out to about 90 degrees, which is parallel to the floor. Slowly return to starting position. I use a resistance band here, however to progress you can either tighten up the band by holding it closer to your feet or use a dumbbell for this exercise.
FEEL: The muscles on the outside of the shoulder will be working with this exercise.
COMPENSATIONS: Avoid shrugging the shoulder blades as you move into this position.
