Supramaximal contractions are contracting the muscle to a much greater degree that we would ever achieve through regular or extreme exercise. As a result, the intense muscle contractions cause a reduction in fat, and increase of muscle fiber development which builds the muscle and creates a lift and filling effect on the buttocks. EMSCULPT, when used on the abdomen, is slightly different. It uses the same technology but the device is programmed to use the high-intensity focused electromagnetic software to reduce fat as well. EMSCULPT for the buttocks is programed to lift, fill and firm.
