2. Don't drink plenty of water before exercise. It is recommended to drink a small amount of normal saline.
Don't wear soft-soled shoes for running, high jump and long jump, and the shoelaces should not be too long.
Try to go to bed early the night before, check the sports equipment and do something that usually makes you happy.
5. Avoid taking water that is too cold. Because people's body temperature is usually around 37℃, it can rise to around 39℃ after exercise. If you drink too cold water, it will strongly stimulate the gastrointestinal tract, causing gastrointestinal smooth muscle spasm and sudden contraction of blood vessels, leading to gastrointestinal dysfunction and indigestion.

Precautions:
Be sure to do warm-up exercises before fitness to protect your body from injury during fitness. The preheating time is about 5 minutes.
The amount of exercise depends on your physical condition. If possible, ask a personal trainer to arrange a fitness plan reasonably. Don't overload your exercise at the beginning for the sake of speed, which will hurt your health.
