Hello, Asian Sports Federation will answer for you: the place where the girth is measured must be accurate first. According to the differences between men and women, the order of body fat accumulation should be abdomen, buttocks, thighs and whole body. When reducing fat, fat will be consumed in the opposite principle. Then exercise is muscle contraction, and subcutaneous fat will attach to the muscle together with superficial fascia. Then the tighter the muscle, the smaller the circumference of fat will be. At the same time, the weight difference between muscle and fat in the same volume will reach 10 times. Muscle is much heavier than fat, so it will cause your circumference to become smaller, but your weight will increase.
