As we all know, you must wear sports shoes. Soft and shockproof sports shoes can absorb the pressure from the ground, slow down the impact on the feet, and indirectly reduce the chance of sprain. They are necessary equipment to prevent sports injuries.

2. Smoking is forbidden. Because nicotine promotes capillary contraction and hardening, reduces exercise effect and consumes vitamin reserves in human body.

3. No exercise after meals. It is unscientific to exercise immediately after meals, so we should advocate normalization and enter the gym one hour after meals. But don't be short of water before, during and after exercise, and don't drink plenty of water.

4. Don't talk loudly and keep silent, otherwise it will destroy the rhythm of movements, make the quality and quantity of movements difficult to guarantee, and the exercise effect will be greatly reduced.

5. Don't laugh and joke during exercise. Overload exercise must concentrate and go all out. Joking will distract athletes or make them stop laughing, thus destroying the rhythm of action.
