HOW: Anchor a band at about elbow height. Place a towel roll underneath your arm in your armpit. Hold onto the band with the hand closest to the anchor. Keep your elbow at your side but bend your arm up creating a 90 degree “L” shape with your knuckles facing forward. Step away from the anchor for resistance. Quickly and in control, rotate your arm inward performing internal rotation of the shoulder.
FEEL: You should feel your shoulder muscles working.
COMPENSATION: Keep that 90 degree “L” shape in your elbow at all times.
