As for whether not exercising muscles for a long time will decrease, we can analyze it like this. Through exercise, a person can first improve the body's muscle mass and increase the body's muscle mass. At this time, the muscles of the body are growing in quality and quantity. If a person doesn't exercise for a long time, the muscle quality will first decline, which is mainly reflected in the fact that muscle strength and endurance are not as good as exercise.

If you don't get exercise, your muscles will start to shrink and the number of muscles will decrease. Therefore, if a person does not exercise for a long time, his muscles will decrease. Exercise can not only improve muscle mass and increase muscle mass, but also delay muscle atrophy caused by age.

Fitness exercise is not as complicated as many people think, and it does not need professional fitness equipment, special fitness venues or enough exercise time. You just need to run 10 minutes, do push-ups, do squats with your bare hands and so on. And do it every day. Fitness is persistence. If you don't want to lose your muscle mass or your muscle mass, please keep exercising every day.

Regarding whether long-term inactivity will reduce muscle, I believe everyone can get their own answer through the above explanation. It is painful for us to exercise our muscles. After we exercise our muscles, we should do it step by step. We shouldn't give up exercise at once. If you want to maintain your muscles, you still need regular strength training.
