How does Slendertone Work?

Slendertone’s Electronic Muscle Stimulation technology (EMS) uses a gentle current to contract your abdominal muscles, Slendertone ab belt works using a unique three-pad placement configuration which ensures that all muscles in the targeted region are exercised properly by stimulating specific, relevant nerve-clusters over the whole area. The result is strong, deep, comfortable contractions that, over time, train your muscles to be firmer and stronger.
Our abdominal toning products work by targeting not just the muscles you can see, but also the muscles that are more difficult to reach with conventional exercise. The rectus abdominis (upper and lower), obliques (which shape the waist) and the transversus abdominis (deepest core muscle that acts as a girdle) are all activated. The transverusus abdominus is essential for stability in the lower back region and is very difficult to reach with conventional exercise.
Slendertone EMS technology has been used for over 50 years in hospitals, clinics and physical therapy practices around the world to strengthen and rehabilitate muscles:
Slendertone EMS technology ab belt stim and nerves activated Slendertone EMS technology ab belt stim through pads Slendertone EMS technology ab belt stim through pads and nerves

Signals are sent among the 3 medical-grade GelPads™ reaching the nerves that branch out to the major abdominal muscles causing deep, strengthening contractions that with repetitive action strengthen, tighten and tone your abdominal muscles.
