Features:1. Aiming at the various muscle groups and fat parts of the body, burn fat while sculpting the body, killing two birds with one stone and achieving quick results. EMS is distributed on the chest, arms, back, buttocks, front and back of thighs.2. The human brain provides bioelectric signals to the limbs and trunk to stimulate muscle movement.3. By transmitting the medium and low frequency pulse current to the muscle motor nerve through the flexible and conductive sportswear medium, it simulates the bioelectric signal of the human brain.4. Adjust the pulse, intensity, frequency and interval time as needed, so as to safely and effectively let the muscles move independently to achieve synergistic effects, such as strengthening or shaping, reducing fat and relaxing muscles. The frequency range of EMS pulse is 200HZ to 2000HZ, respectively in the abdomen, arm, chest and thigh area, can effectively penetrate more than 90% of the muscle layer.5. The effect of using EMS during exercise is similar to strengthening the resistance by increasing the weight. The higher the frequency, the heavier the resistance. Therefore, it is recommended that users use about 30 minutes during exercise, which is equivalent to 2 hours of high-intensity training.
