HOW: Standing by a wall, bring your elbow up at your side to shoulder height. The elbow should be against the wall. With your arm starting up creating a 90 degree bend in the elbow, bring your hand back and forward while keeping the elbow in the same position. Think about rotating in a pure axis that is draw between your shoulder and your elbow.
FEEL: You should feel the muscles in your shoulder working.
COMPENSATION: Don’t let your elbow fall below shoulder height while rotating on the wall. Don’t lean your body back while rotating back or forward while rotating to the front.
