The first thing to be clear is why you gain weight. There are several main aspects of weight gain. First, the calorie intake is greater than the calorie consumption. At this time, excess calories will be stored in the body in the form of fat, leading to weight gain. This is also the most common one. Second, increase the resistance training of muscle mass. Because the same volume of muscle is about 4 times heavier than fat, that is to say, when you do some muscle building training, your body shape may not change, but your muscle mass has increased. So I gained weight. This is what many muscle builders expect. Third, pathological weight gain. This is more complicated and changeable. For example, the dysfunction of some organs will lead to problems in water metabolism in the body, and a large amount of accumulated water in the body cannot be eliminated, which will lead to weight gain.

Lz said, if you weigh at a fixed time and weighing scale, and you don't drink much water before measurement, it is mainly a combination of the first case and the second case. This problem is more likely to happen, especially when a person never exercises before starting to exercise. Because many people just start exercising, it will make the body uncomfortable and the body's usual calorie consumption will be broken. At this time, the body will send a signal to make you hungry, and you may eat more calories than you consume in your diet. Secondly, although running is aerobic exercise, it will also develop the muscle endurance of the legs. After this, the muscle mass will also improve, so the weight will increase. This is no problem.

If lz wants to shape and lose fat, don't focus on the change of weight, but pay more attention to the change of body fat content. This is the most critical index that affects your training effect.
