HOW: Start by looping a band around your wrist. Stand close to a wall with your elbows on the wall straight out from your shoulders making your palms face each other. Keep your elbows in as you create tension in the band with your shoulders. Keep one arm stable as you move the other arm slightly in, up, and then out holding that tension on the wall once you go out. Repeat on the other side going up and down.
FEEL: You should feel your shoulder muscles working.
COMPENSATION: Don’t create tension in the band with your wrist or hands, keep them relaxed and only use your shoulders. Keep a bend in your elbow, even when you move up and down on the wall. Keep your back up straight, don’t lean forward or backwards.
