HOW: While standing, place the band around your wrist with your palms up facing the ceiling. Squeeze your shoulder blades back and create tension in the band by moving your arms out. Keep the tension in the band as you move your arms forwards in front of you and back down.
FEEL: You should feel the muscles in your shoulder working.
COMPENSATION: Always keep some tension in the band. Don’t let your wrist come in and loose tension.
