People who exercise will have a special point, that is, people who exercise regularly are muscular. We will also find that in many countries on earth, due to differences in eating habits, people in some countries will be more muscular, but after a long period of inactivity, their muscles will shrink and their body fat will increase. This will happen. As long as they don't exercise, their muscle fibers will become thinner, and because of diet, the fat responsible for muscle fibers will become thicker and thicker in daily life, so it is more likely to cause muscle atrophy.
In addition to long-term inactivity, we will also find that some conditions can easily lead to muscle atrophy, such as congenital diseases, which are difficult to cure or treat. Moreover, due to the change of our eating habits, there are still high calories in food, which is more likely to cause people to produce more fat and cover muscles, so muscle atrophy is more serious.
And this is constantly reminding us that exercise is essential to keep fit and healthy muscles for a lifetime, so it is also of great benefit to your body, not only to lose weight, but also to play a role in fitness. In short, after people do not exercise for a long time, muscles will shrink because of the thinning of muscle fibers and the coverage of fat.
