1. The main purpose of going to the gym is to improve the performance of the 200-meter run, right? If that's the point, I advise you not to go to the gym. Because the 200-meter run measures your speed endurance, the gym has no conditions to exercise your ability.

The best way is to strengthen the practice of 200-meter running. If there is a 200-400-meter-long straight road near your home, you'd better practice safely. If not, I suggest you practice in physical education class or in the school playground after school.

3. The best way to improve the 200-meter run is: 1) Run more than 200 meters at your maximum speed, and the distance of each run can be gradually increased (for example, run 250 meters in the first week, 300 meters in the second week, 350 meters in the third week and run in the fourth week). . . . )。 Finally, it is best to run 400 meters at a time. 2) During each exercise, arrange 2-3 groups of running exercises, with each group running 3-5 times. Rest for 2-3 minutes after each run, and rest for 5- 10 minutes between each group.
