This perception of muscle is actually an illusion, because muscle and fat are two completely different tissues in the human body, and they will never transform into each other. People who feel inactive or exercise in the wrong way are bloated only because the ratio of fat to muscle in the body has changed.
Physiologically speaking, muscle will never become fat, and fat will never become muscle. Some bodybuilders or athletes do get fat after stopping training, especially football players and weightlifters. During the training period, because of the high calorie consumption, their appetite will increase accordingly. But when they stopped training, their appetite didn't drop at all, so their calorie consumption in the body was greatly reduced. Therefore, if the diet plan is not adjusted accordingly, the daily intake of calories is bound to be greater than the consumption of calories, resulting in fat accumulation.
Therefore, people who usually exercise a lot will not accumulate too much fat as long as they adjust their diet and reduce their calorie intake after stopping training. Of course, without the stimulation of strength training, muscles will gradually lose. In order to avoid this problem, we should do proper strength training every day.
The so-called strength training is actually a kind of exercise that uses resistance to cause muscle contraction, thus promoting the growth of muscle strength, endurance and girth. Including unarmed training and weight-bearing training. Unarmed training mainly includes push-ups, pull-ups and sit-ups, while weight-bearing training requires the use of barbells, dumbbells and other weight-bearing equipment for strength training to promote the growth of muscle strength and circumference.
