HOW: Begin by standing at a cable machine or resistance band set, facing away. Set the stack at about hip height. Taking the handles to shoulder height, find a rotation going towards the back of the body keeping the shoulder blades down. From here, rotate the arms forward until the forearms are parallel to the ground.
FEEL: You should feel the outside of the shoulders working at the rotator cuff. You should feel the inner bottom shoulder blades working at the lower trapezius.
COMPENSATION: Avoid shrugging the shoulders. Avoid straightening the elbows
