During strenuous exercise, the salt in the body is excreted with a lot of sweat. Drinking too much water will reduce the osmotic pressure of blood, destroy the metabolic balance of water and salt in the body, affect the normal physiological function of human body, and even cause muscle spasm. Because in the process of exercise, it is necessary to increase the frequency of heartbeat and breathing to increase blood and oxygen to meet the needs of exercise. Drinking plenty of water will make the stomach full, hinder the diaphragm activity and affect breathing; The increase of blood circulation increases the burden on the heart, which is not only bad for exercise, but also harmful to the heart.

In addition, drinking more water will reduce the concentration of gastric acid and affect food digestion. Drinking water after strenuous exercise for a long time is easy to get stomach trouble.

Because the basic function of exercise is to take in a lot of fresh oxygen from the outside through breathing to meet the needs of health, it is necessary to choose a good place before exercise, and parks, beaches and open-air stadiums are the best.

Before the main physical activity, you should move your limbs with a light amount of activity to prepare for more intense physical activity. The purpose is to improve the efficiency and safety of strenuous exercise and meet the physiological and psychological needs of the human body. Before exercise, the functional ability and work efficiency of human body can't reach the highest level at the beginning, so it is necessary to adjust the exercise state by warming up.
