HOW: Get a band set-up at elbow height and you will face perpendicular to the anchor. You will perform this exercise on one side at a time. Start with your elbow by your side, bent to 90 degrees, thumb facing up, and your hand pointing forward in front of you while holding the band. Then rotate your hand in towards your body while trying to keep your elbow still. Return to starting position and repeat.
FEEL: You should feel the muscles in the front of your shoulder working. Think about keeping your shoulder blade still as you perform this movement and keep that position as you rotate your arm and hand in.
COMPENSATION: Do not shrug your shoulder, do not rotate your entire body, keep your shoulder still, do not move at your wrist.
