This series is great for anyone who spends a lot of their time in a forwardly rotated shoulder position, including those who spend a lot of time driving, working on a computer, or just suffer from poor posture in general. Do you have trouble getting your arm up over your head or scratching your own back? Do you suffer from upper-back/shoulder pain and tightness? If so, this series may be just what you need to get you feeling free to move those arms like they were meant to move: PAIN FREE!
