Electronic muscle stimulator for fitness is useless. That kind of thing can't produce creatine, muscle can't swell, and only consumes a small part of fat. Other dissolved fats will accumulate in your body because they can't be discharged, which is more difficult to eliminate. Simply put, it's useless except relaxing muscles. This instrument only stimulates muscles through micro-current, and fitness are two concepts. Fitness still needs active exercise, not passive equipment. Muscle is the product of human body's daily exercise. When you electrically stimulate a muscle, you can only say that your feeling for the muscle will get better immediately, but it is not. At present, there are many vibration products, and the electronic ones are only the evolution of vibration. No matter what weight loss products or weight loss products are on the market, they may have short-term effects, but they will rebound greatly after use.
