This exercise can be very healing when recovering from a shoulder injury. Stand about hip width apart. If you tend to overstretch your joints like me, keep a micro bend in your knees. Your left foot is on your resistance band. With the right hand, grab the band. Move it with straight arms from the left hip to the right side of your body. Also in your elbows, you can keep a micro bend to protect your joints. Try to limit the movement to your shoulders and don’t do it with your core. This is supposed to be a shoulder exercise.
