Working Principle This beauty muscle instrument uses non-invasive technology of high-intensity focused electromagnetic wave to release high-frequency magnetic vibration energy through two large treatment handles to penetrate the muscles to a depth of 8cm, and induce continuous expansion and contraction of muscles to achieve high-frequency extreme training, to deepen the growth of myofibrils and produce new collagen chains and muscle fibers, thereby training and increasing muscle density and volume. Features 1.Dual effects —— achieving muscle building and body slimming effectively. 2.Safe and easy —— no knife, injection, medicine, current, radiation, exercise, diet, pain, side effect or recovery period. 3.Time & effort saving —— lying down for 30 minutes =49500 times of muscle contraction = 49500 times of sit ups / squats. 4.Quick & remarkable results —— a course of treatment can effectively increase muscle by 16% and reduce fat by 19%. 5.Multi-applicable positions —— precise treatment on abs, arm, shoulder, leg or hips, etc. 6.Two handles —— operating simultaneously and effectively, suitable for men & women.
