Using EMSlim (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,that is, the growth of muscle fibrils (muscle enlargement) and produce new protein chains and muscle fibers (muscle hyperplasia), so as to train and increase muscle density and volume. The 100% extreme muscle contraction of EMSlim technology can trigger a large amount of fat decomposition,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.
