10-year-old children mainly participate in aerobic exercise, so it is best to maintain a high frequency of aerobic exercise, and it is best to participate in physical exercise with a certain intensity at least three times a day and week. The content of exercise can be eclectic and consists of many parts, including games, play, sports activities, labor and entertainment. When participating in sports activities, you should engage in various sports involving most muscle groups. Including brisk walking, basketball, football, swimming, cycling and so on. This kind of exercise can promote the mental health of teenagers and improve their cardiopulmonary function.

Take part in exercise for more than 20 minutes at a time, mainly depending on the frequency of taking part in exercise. If it is three times a week, the time needs to be extended appropriately, and you can choose about 40 minutes. If the exercise frequency is high or you participate every day, the exercise time can be slightly shorter, but the duration of each exercise should not be less than 20 minutes.

Try to avoid high-intensity strength training. The intensity of strength training is lower than medium, and it should be carried out under certain monitoring conditions. The load should be 1/3~2/3 of one's own weight. The combination of exercise to improve muscle structure and exercise to develop flexibility is beneficial to the overall improvement of teenagers' physical fitness.
