Primary Muscle Group: Shoulder
Muscle Groups Worked in This Exercise: Rotator Cuff
Preparation: Attach your band to a door anchor or suitable object at elbow height. Since you'll be using one handle, be sure to anchor the other end securely. Stand sideways to the anchor point with the band on the opposite side that you are working. Grasp the handle with your palm in and bend your arm at 90 degrees at the elbow. Keep your arm tight to your body and rotate your shoulder so your forearm is across your body.
Breathing: Exhale as you move your arm out to the side; inhale when returning your arm back to the side of your body.
