HOW: Anchor a resistance band about wrist height onto a stable surface. Keep your hand directly in front of you, then walk out as far as you feel comfortable to create tension on the band. Keep your shoulder blade pulled back while performing this. I keep a towel under my elbow for comfort.
FEEL: You will feel muscles on the back of the shoulder work with this exercise.
COMPENSATION: Avoid moving the arm with this exercise, this is designed to be an isometric exercise.
