Adopting HI-EMT (High Energy Focused Electromagnetic Wave) technology to continuously expand and contract autologous muscles and carry out extreme training to deeply reshape the internal structure of the muscle. The growth of muscle fibrils (muscle enlargement) produce new protein chains and muscle fibers (muscle hyperplasia) and then increase muscle density and volume. The 100% extreme muscle contraction of HI-EMT technology can trigger a large amount of fat decomposition. And fatty acids are broken down from triglycerides and accumulated in fat cells. The concentrations of fatty acids are too high, causing the fat cells to apoptosis, which is excreted by the body's normal metabolism within a few weeks. Therefore, Slim Beauty Machine can strengthen and increase muscle, and reduce fat at the same time.
