The Smart Relief Massage Belt is specifically designed to give optimum relief for the lower back. The lumbar region of the back takes a pounding. Over time work, stress, age etc all take their toll. Once the muscles knot up, it takes a lot to unlock them and relieve the tension on the nerves in that area. Our specially designed belt allows three extra large pads and the device to be held securely in place. Once the belt is worn, you can go about your day and continue to receive pain relief for as long as you like. The Smart Relief Massage Belt is also used to help tone your abdominal muscles.This works by wrapping the belt around your core and stimulating your stomach muscles. The ab belt works by transmitting electrical pulses through your stomach that will cause your abdominal muscles to contract involuntarily, thereby providing an easier way to burn fat. The Smart Relief Workout Belt exercises your muscles for you. So place the Workout Belt on and go about your day and let the belt do the work for you.
