First: Never warm up when exercising. Don't think that doing warm-up exercises before fitness is a waste of centuries. If you don't do warm-up exercises, it is easy to bring fatigue and injury to your muscles and joints, then arthritis and fractures are likely to find you.
Second: Blow the air conditioner immediately after fitness. Many people want to enter the cool air-conditioned room immediately after sweating after fitness. In fact, after fitness, the physical strength of the human body will be relatively weak, and the resistance will be relatively reduced. At this time, germs are easy to attack. If the air conditioner is blown immediately after exercise, the pores will expand and then the germs will invade. The correct way is to take a hot bath in an hour. Don't suddenly cool down, give your body a stable temperature environment.
Third: no nursing equipment was used. In the gym, many people leave sweat after exercise. If these instruments are not disinfected with alcohol, many people will have skin diseases and infect each other after using them. Therefore, you can prepare alcohol before fitness, disinfect the equipment used for fitness, and then continue training.
Fourth: poor sleep quality. Many people like to stay up late very much, and then they don't have enough rest time during exercise. At this time, the cells in the body have not been fully rested. This will affect the effect of fitness and make the body too tired.
