Hi-EMT is a magnetic thin instrument that uses high-intensity focused electromagnetic wave energy to burn fat and build muscles . It generates a unique electromagnetic energy, through the skin to stimulate super muscle contraction, deep remodeling of muscle internal structure, That is, the growth of myofibrils (muscle enlargement) and the production of new protein chains and muscle fibers (muscle hyperplasia) to train and increase muscle density and volume. During this process, resulting in a large amount of fat decomposition, fatty acids flow out from the breakdown of triglycerides and accumulate in large amounts in fat cells. When fatty acids are too high, fat cells die and are excreted by the body's normal metabolism within a few weeks.
