You should make one according to your physical condition. A healthy diet. Then stick to it. When you are free at school, you should sit there and play computer games less, go out for a walk, take a walk, play ball, badminton and basketball, especially after meals. Students with good willpower can go for a walk after dinner. Run before going to bed, have a rest after dinner, take a walk, go shopping, then run twice and do an aerobic exercise to enhance your basic metabolism for about 20 minutes. Just jogging. Because of the limited school conditions, instead of going to the gym to do diversified sports, jumping and doing aerobics, you can run around the playground and take a walk at school, which is quite good, helping you digest your body and promote circulation.
