If the intensity or amount of exercise exceeds the limit that the human body can bear, the body will overreact, causing unnecessary damage and leading to the decline of human immunity. However, the intensity and amount of exercise is by no means as small as possible, and the body can't reach a certain "load" and can't play the role of exercise. Therefore, we should strengthen the awareness of gradual progress and prevent improper exercise.

For teenagers, especially teenagers, we should choose sports that are conducive to the all-round development of physical fitness, such as running, jumping, throwing and ball games.
