Exercise consumes energy and promotes the oxidative decomposition of fat stored in the body, thus reducing fat. But at the same time, frequent muscle contraction and exertion during exercise will stimulate muscle fibers to thicken and increase muscle mass. In the body, the water content of muscle tissue is much higher than that of fat tissue, so muscle is "heavier" than fat (strictly speaking, on the premise of the same volume). In other words, as long as the muscle "less" increases, it will offset the weight loss caused by the "more" reduction of fat. Eventually, the weight loss before exercise is not obvious.

Fat consumption is directly related to the amount of exercise. No matter what kind of exercise or form, as long as the amount of exercise is large enough (enough energy consumption), it can promote the oxidative decomposition of fat in the body. However, the increase of muscle is directly related to the form of exercise. Generally speaking, the more strenuous exercise (such as weightlifting, dumbbells, equipment, etc. ) is necessary, the greater the stimulating effect on muscle growth, because the formation of muscle follows the principle of "use is life, use is retreat". In addition, the increase of muscle is most obvious in the early stage of exercise, especially for people who have never exercised before and are just beginning to exercise now. If you continue to exercise, that is, exercise for a long time, your muscles will not keep increasing. Therefore, the best way to solve the problem of not losing weight in the early stage of exercise is to build up confidence and continue to exercise until the weight gained by muscle can't offset the weight lost by fat, and the weight will naturally drop. At the same time, we should pay attention to choosing the right exercise form to avoid excessive stimulation of muscle growth.

Of course, it must be explained that, in any case, the increase of muscle is beneficial to health. That is to say, I have lost fat and gained muscle. Although I haven't lost weight, I still have great health benefits, at least not lower than ordinary weight loss. Regardless of health, lose fat and gain muscle. Although the weight has not decreased, the "volume" of the body has decreased, so people will appear "thinner" and more energetic.
