THE SAVE YOUR MIDDLE BACK DVD teaches you how to keep your thoracic vertebrae and ribcage area unrestricted. If this part of the spine is compressed and tight it can cause lower and upper back problems. It also houses your lungs and heart and so the more freedom you have in this area the better this is for your circulation and all-round body performance. *Always begin with the lower back work and then move up the spine to middle back.
