HOW: Get set-up in a golf stance position with bands anchored in front of you at about waist height or lower. Criss-cross the bands and hold them in front of you with your arms straight. Perform a T motion bringing one arm out to the side while keeping the rest of your body still. Slowly return to starting position, repeat on the other side.
FEEL: You should feel your entire body working, from your legs and core maintaining body position, your shoulder and upper back muscles working to move the arm.
COMPENSATION: Do not lose your golf stance position, do not shrug your shoulders
