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 other one still. At the same time, rotate your body in the same direction as the moving arm as far as you can with good form. 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, and your core and mid-back muscles working to rotate your body.
COMPENSATION: Do not lose your golf stance position, do not shrug your shoulders.
