How do bodybuilders train?

Bodybuilders are generally divided into seasonal and non-seasonal. The four seasons are as short as three months and as long as six months. In the off-season, more efforts are mainly made on diet, that is, sudden weight gain and crazy intake of various fattening foods. Training in the gym is nothing more than two purposes: reducing fat and gaining muscle. But in fact, while gaining muscle, it will inevitably increase the body's fat content, and reducing fat will inevitably reduce the body's muscle content. We ordinary amateurs tend to lose fat slowly and gain muscle at the same time. A big difference between fitness and bodybuilding is that there is no specific period to gain muscle and lose fat, and there is no deliberate requirement for diet. The requirement is to gradually gain muscle and lose fat, but the speed is slow and it is easy to encounter bottlenecks, but the advantage is relatively healthy. Professional bodybuilders are the opposite. They usually add a basic diet after intensive training every day in the offseason, mainly to gain muscle, and the side effect is that body fat will also increase. In the following season, they increased the intensity of training, controlled their diet (but the diet they controlled was actually very large compared with ordinary people), brushed off the fat outside the muscles and exposed the lines. There are still terrible things to do in the season, such as dehydration, as follows: two weeks before the game, you must drink one or two barrels of bottled water every day (that is, bottled water on the water dispenser). As a result, the kidneys are used to this intensity of urination, and then they run stairs in cotton-padded jackets three days before the game without entering the water. Because the kidneys are used to the previous amount of urination, these three days are the same, and they can be dehydrated quickly. This will make the muscle lines more exposed and the muscles clearer.
