The preciousness of sports lies in adhering to a well-said saying: "Running water does not rot, and the householder does not rot", clarifying the truth that "sports are not lasting" and emphasizing the importance of continuity and uninterrupted. This view coincides with one of the principles of sports health-persistence. Only by persisting in sports to the end can we fundamentally improve our physical fitness and health level. If you take the method of fishing for three days and drying the net for two days, you can't achieve the purpose of fitness and health preservation at all.
The ultimate goal is to improve health by mastering the sense of proportion and not exercising excessively. If the amount of exercise is not well controlled, it will not only fail to achieve the expected goal, but will be harmful to health. To sum up, the amount of exercise is too small to achieve the purpose of exercise and the role of fitness; Excessive exercise will exceed the body's endurance, but it will damage the body because of overwork. Sun Simiao, a famous doctor in the Tang Dynasty, pointed out in the medical classic "Prepare for a Thousand Gold Prescriptions": "The way to cultivate temperament is often hard work, and it is extremely tiring and the strong are not heard." This means that the key to keeping healthy is to exercise regularly, but not too much. If you feel tired, it will be bad for your health. Therefore, exercise and fitness emphasize moderate exercise, step by step, and don't rush for success. Make haste slowly.
