HOW: Anchor a band about shoulder height. Face the anchor and grab onto it with one hand. Bend your elbow and raise it up to the side at shoulder height. Start close to the anchor as you bring your arm up to make a “L” position with your elbow straight out from your shoulder and your hand pulling the band to where your knuckles are facing up. Hold that position as you walk backwards until you feel the right resistance for you, and then walk forward to repeat.
FEEL: You should feel your shoulder muscles working.
COMPENSATION: Maintain the 90/90 position as you walk backwards, don’t drop your elbow down. Keep your trap muscles relaxed.
