HOW: In a standing position, anchor a band underneath the foot of the arm you want to work. Bring that band up to where it is on each side of your bent elbow and have your fist facing backwards. Rotate the arm out to have your fist facing forwards and elbow almost at shoulder height. From here, press the band up overhead. Then, reverse the rotation back to the starting position.
FEEL: You should feel your shoulder muscles working.
COMPENSATION: Don’t lean to the opposite side once you rotate and press the band out and up. Don’t shrug your shoulder, keep your upper trap muscles relaxed.
