Weight loss instruments generally use vibration to promote the decomposition of local fat by heating and separate the body surface through lymphatic circulation. If you shake at this time, the microvessels in the relaxed muscles will be compressed or even broken, resulting in congestion of the muscles, so the muscles will become hard.

If you use instruments to reduce abdominal muscles, you can practice arm strength, arm reduction and thigh training. Equipment should be used with exercise to achieve good results.
