The NASA-designed motor sends powerful sonic waves to the fat, causing your body’s natural processes to step up and burn the fat, contract the muscle and reduce the pain…With the Ston-O-Max, your body will receive more oxygen to your muscles. To handle that extra oxygen, your veins and capillaries expand, letting in not only more oxygen, but also more nutrients. There’s even a built-in infrared heating massager that is tantamount to receiving a professional rubdown after a strenuous workout.
