The energy of electromagnetic field output by EMSzero, a non traumatic technology, can safely generate the same frequency resonance with muscle neurons, with the purpose of triggering super muscular contraction and increasing muscle mass. Using HI-EMT technology to continuously expandand contract muscles, perform extreme training, deep remodeling of the internal structure ofmuscles, that is, the growth of myofibrils and the generation of new proteinchains and muscle fibers to train and increase muscle density and volume..syi
