Waist twisting is to stimulate the soles of the feet naturally and repeatedly by stepping on the magnetic massage cushion with the help of the user's own weight, and to arouse the power of various organs of the human body through the conduction of peripheral nerves and the effect of magnetic therapy. With the twisting motion of the left and right waist, the magnetic wave is transmitted to all parts of the human body, and a vortex-like secondary current is generated in the human body, thereby eliminating the excess fat accumulated in the body (especially in the abdomen and waist), thus achieving the effect of strengthening the body. The main function is to exercise waist muscles, make the waist more flexible and reduce waist fat.
