HOW: Begin in a plank position onto a foam roller while holding onto a resistance band with both arms. Your feet, hips, and shoulders should all be in one straight line. You will then roll out primarily driving with the shoulder blades while keeping tension on the band. Go out as far as you feel comfortable.
FEEL: The core will be working throughout this exercise. The target muscles here are the muscles on the shoulder blade and the back of the shoulder.
COMPENSATION: Avoid arching the back as you perform this exercise. Also, avoid bringing your hands in together.
