Arm Up Rotator Stretch
Description
The arm-up rotator cuff stretch is a flexibility exercise where one arm reaches up and behind your head while the other arm reaches up your back from below. The hands meet behind the back, stretching the rotator cuff and improving overhead and behind-the-back shoulder mobility. A towel can be used to assist if your hands cannot meet.
