Fitness can shape, and people who exercise regularly, whether boys or girls, look better in clothes than those who don't exercise. Fitness can also enhance resistance, which is very helpful to a person's health. Usually some small colds or something, because of the strong resistance brought by long-term fitness, may not take medicine. People who insist on fitness for a long time must be very self-disciplined, and those who are not self-disciplined are hard to persist, so fitness can also form the habit of self-discipline.
