It is recommended to jog at 06: 30 in the morning (clothes in winter, thick in summer and thin in summer, no shorts, sweating to keep warm), and slowly alternate running or running the standard 400-meter track on the sports field. After the first three laps, the body enters a slightly hot state, and then the feet jog hard for 4 laps at a medium speed with striding or striding, and running for 5 steps is properly called sucking (hitting 3, sucking 2). When the body enters the whole foot with a slight sweat and slows down slightly, run for another 5 laps. After jogging with slight sweating, do some relaxing activities in a difficult running state, such as walking, jogging, squatting, waist and chest. Take your temperature, your heart rate returns to normal, and then go back to your room. When you go back to the back room, you'd better put on sweaty clothes, or consciously put on a sweatshirt before the game and finish drying. You should wash it three times.
