Subtracting 10 kg body weight may include 4 kg water, 2 kg feces, 2.5 kg muscle and 1.5 kg fat. Fat density is small, like foam. If a person really loses 10 Jin of pure fat, then his body shape will be greatly improved. But in reality, many women have lost 10 Jin, but their figure has not changed. It is precisely because of the wrong way to lose weight that the thin 10 Jin has only a little fat. Lose more muscle. Women's androgens are low for physiological reasons. Judging from the combination of exercise, nutrition and training methods (small weight, each group 15-25 times), it is impossible to make muscles bigger, only a little muscle density will be increased, that is, the weight will increase, but the volume circumference will not increase. Please rest assured.
