The over-under shoulder stretch increases flexibility in the back, shoulders, and triceps. The exercise also increases shoulder stability and range of motion.
Standing tall, hold the ends of a resistance band in both hands behind your back.
Bend one arm and bring it behind your back, grasping the resistance band as high as possible. At the same time, bend your other arm above your head, pointing your elbow upward and grasping the resistance band as low as possible. Hold, then return to the starting position.
Maintain a flat back and tight core throughout the movement.
