Middle school students are in a critical period of formal physical growth, but considering the combination of work and rest, there are realistic pressures such as further studies, homework and extracurricular classes, you might as well do the following things:

1, high-quality daily practice between classes (it's cool to do every movement without dragging your feet)

2. Take physical education class seriously (physical education class usually gives 10~ 15 minutes of free time except for teachers. At this time, you might as well do some sports you like, such as playing ball and parallel bars. Too many female students hide in the corner and even eat snacks as soon as they are free).

3. Ride to and from school as much as possible (there is not much exercise time, so why not give yourself a chance to exercise).

4. Coordinate a designated exercise time (for example, ask a few regular classmates to run, play ball and swim together on weekends).
