There are many ways to exercise. In addition to the common exercise methods in teaching and training (including repetition, transformation, synthesis, circulation and competition), people have formed various eclectic fitness methods in long-term exercise practice (including morning exercises, interval exercises, production exercises, Cooper 12 minute test, etc.). ).
The determination of exercise content and methods and the whole exercise process should follow the principles of physical exercise, that is, pertinence, adaptability, step by step, perseverance, appropriate load and emphasis on exercise value. In addition, if we can use China's traditional fitness methods at the same time, such as the combination of form and spirit, static and dynamic, and internal and external combination, the effect will be even greater.

Practice instructions
First, avoid exercising under strong light.
Around noon, the hot sun is in the sky and the temperature is the highest. In addition to swimming, avoid exercise at this time and beware of heatstroke. In summer, the ultraviolet rays in the sun are particularly strong, and human skin can be burned by I ~ II after long-term exposure. Ultraviolet rays can also penetrate the skin and bones, radiate to the meninges and retina, and cause damage to the brain and eyeballs.
Second, avoid too long exercise time.
An exercise time should not be too long, generally 20 ~ 30 minutes is appropriate, so as to avoid excessive sweating and high body temperature, which may cause heatstroke. If you exercise for a long time, you can arrange 1 ~ 2 breaks in between.
Third, avoid drinking plenty of water after exercise.
A lot of exercise and sweating in summer, so drinking a lot of water will increase the burden on the blood circulation system, digestive system, and especially the heart. At the same time, drinking water will make you sweat more and further lose salt, which will cause convulsions, cramps and other symptoms.
Fourth, avoid taking a cold bath immediately after exercise.
Because the heat generated by summer exercise increases rapidly, the capillaries of the skin also expand a lot, helping the body to dissipate heat. Sudden supercooling stimulation will suddenly close the pores that have been opened on the body surface, leading to disorder of internal organs of the body, abnormal temperature regulation of the brain, and even illness.
5. Avoid eating a lot of cold drinks after exercise.
Physical exercise can make a lot of blood rush to muscles and body surface, while the digestive system is in a state of relative anemia. A large number of cold drinks not only reduce the temperature of the stomach, but also dilute the gastric juice, which can cause indigestion and acute gastritis.
6. Avoid drying clothes at body temperature after exercise.
In summer, sweat is secreted more, and clothes are almost soaked. Some young people rely on their physical fitness and are often lazy to change their undershirts, which is easy to cause rheumatism or arthritis.
