Getting a muscle spasm or pinched nerve on your chest or back while doing chores at home or carrying heavy items at work can be a very painful experience. Such an incident can become a health risk when the pain doesn’t go away, you’re all by yourself, and you’re too weak to move and get help from the neighbors. This problem can be attributed to either a lack of oxygen in the body, poor blood circulation, or stress. The Arched Back Stretcher is the therapeutic back support which you need to gently relieve the tightness and tension felt in your muscles and nerves by doing some easy and workable back-stretching floor exercises.
