DESCRIPTIONAttach one end of a resistance tube to something about chest height. Holding the other end of the tube in your right hand, take a few steps back until there is some resistance in the tubing.
With your left side facing the attachment point, have your right upper arm against your side, your elbow bent to 90 degrees, and right hand pointed towards the attachment so your forearm is against your stomach.
Exhale as you rotate at the shoulder to move your hand out until it points all the way to the right. Inhale as you return to starting position, and repeat all reps.
Next, face your right side to the attachment, tube still in your right hand, upper arm against your side, elbow bent at 90 degrees, and hand pointing towards the attachment. Exhale as you rotate your shoulder until your forearms is against your stomach.
Inhale as you return to starting position, and repeat all reps.
Alternatively, you can perform this exercise by lying on your side and using a dumbbell.
