Living a self-disciplined life can also have a good figure. It is necessary to develop good living habits, such as going to bed early and getting up early, and having a regular life routine. If you stay up late for a long time, your life will be irregular, which will affect your mental outlook, reduce your immunity, and lead to endocrine system disorder, which is undoubtedly unfavorable for keeping fit. If you exercise, you need enough rest time to ensure the repair of your body.
