The Slendertone website features various testimonials that state that the Slendertone Abs belt works. Slendertone Abs is clinically proven to give the user stronger and flatter abdominal muscles in as little as four weeks.
Slendertone belts use Electronic Muscle Stimulation (EMS) technology to force the abdominal muscles to contract. Similar technology is used in hospitals for the rehabilitation and strengthening of muscles. The Slendertone Abs belt also activates muscles that are hard to reach by doing traditional abdominal exercises. Most users of the belt report stronger, firmer muscles. In addition, a six week case study conducted by Slendertone Abs proves that using this product correctly will visibly strengthen abdominal muscles.
