【Product Features】 This training gear uses EMS (Electrical Muscle Stimulation) to train muscles, leading to a toned physique. This product employs a 20Hz frequency, which efficiently trains muscles, developed through research by Professor Toshio Moritani, Emeritus Professor at Kyoto University and a world authority on EMS. Powersuit Lite Abs stimulates and trains abdominal muscles by passing electricity through the electrodes. The use of water sprayed on the fabric electrodes (Eledeine) allows for stable electrical conductivity, eliminating the need for replacement gels.
