A: This is a normal weight change. Your weight gain comes from the increase of water in muscle volume, but it is mainly the increase of water. When our muscles are not trained, energy, nutrition and water are relatively low, because storing too much is meaningless to muscles. When you start training, muscles need energy, nutrition and water very much, so these substances will come to muscles with water in the short term of training, which is reflected in the increase of muscle volume and strength, but you should know that this is an illusion, not the growth of muscle fibers themselves, but the filling of more substances.
Generally speaking, the weight gain of beginners in one month is: 1-5 kg. In particular, the effect will be more obvious if you eat muscle-increasing powder, a sports nutrition supplement that is very suitable for you.
