Introducing Hi-Tone XL, the ultimate Electro Muscle Stimulation and Contouring Machine that utilizes EFWT (Electromagnetic Focused Waves Technology) to induce supramaximal muscle contractions that cannot be achieved through voluntary action. This leads to a deep remodeling of the muscle’s inner structure, resulting in muscle hypertrophy, new protein strands, and muscle fibers, leading to an increase in muscle density and volume. With just 30 minutes of use, you can achieve 30,000 supramaximal muscle contractions. And after only 6 treatments, you can see up to 16% muscle mass growth. Hi-Tone XL is equipped with powerful 7 TESLA magnetic field power on each hand piece.
