It is a fact that children nowadays lack exercise, but it is also a fact that there are hidden dangers in running exercises organized by many schools. In fact, there are many ways to strengthen children's exercise, but children don't have the opportunity to do these exercises, so don't just blame children for not exercising. We should consider why children lack exercise. Only by fundamentally solving the problem can we change the status quo.

First of all, what is the most frequently heard sentence, whether after 90 or 00? What happened to the PE teacher? When we were at school, there was only one section of physical education class every week. Some schools may arrange two physical education class classes, and one class will be counted as 45 minutes. Then the exercise time in a week is only 90 minutes, and the average daily time is only about 13 minutes. Moreover, many students in physical education class actually didn't go to school for a long time, and most of them were dissolved in ten minutes. Therefore, many high school students go to physical education class, which is basically a formality.

Secondly, for people who don't like playing ball games, they may sleep in the classroom for ten minutes between classes, especially for children in Grade Two and Grade Three, who usually sleep late and get up early, so it is easy to doze off in class, so taking a ten-minute break after class is a sleeping time that everyone attaches great importance to. If this is the case for two years, then there is almost no exercise for two years, so many high school students can't run the 800 meters after going to college. This is because of physical problems.

Finally, I hope the school can understand that children's exercise is also very important. Don't occupy students' physical education class at ordinary times, but also make physical education class more meaningful. We should let everyone exercise for at least 45 minutes, but we must master the time and intensity, and never be too strong for children to accept at once.
