The two models you mentioned belong to mechanical weight loss, so mechanical weight loss is the most. She loses subcutaneous fat, because there are three types of fat, the first is subcutaneous fat, the second is renal fat, visceral fat, and the third is vascular acupuncture. That is to say, you use these weight loss methods the most, that is, you lose some subcutaneous fat, so the most harmful ones are visceral fat and vascular fat. This is how you lose weight mechanically. Once the mechanical exercise is stopped, these fats will soon come back. Because these fat cells have memory function, you'd better use nutritious meals instead of exercising every day. And you can get rid of fat smoothly while ensuring your normal life, and you can lose 10 to 30 kilograms of fat a month.
