Hello, if you run 10 km every day, it does have advantages and disadvantages. I'll give you some examples: Advantages: Exercise vital capacity, endurance and leg muscles, and at the same time enhance physical coordination, which has a certain effect on the formation of whole body muscles and has the effect of losing weight. In addition, if you persist for a long time, you can enhance your physical function and improve your health. Running has little effect on the formation of pectoral muscles. If you want to practice your chest muscles, you can try push-ups, pull-ups and swimming. Disadvantages: Daily10km may cause some people to exercise too much, and even have symptoms such as muscle strain, dizziness and nausea. Therefore, it is best to do it step by step according to the individual's specific situation, and it is not appropriate to do such a large amount of exercise at the beginning. Note: Running (or exercising) at night is actually very scientific. Many people think that the air is good in the morning, which is wrong. Because the fog concentration is high in the morning, it is easy to make people breathe hard, which is not good for health. If you exercise at night, because of the photosynthesis of plants, the oxygen purity in the air at night is high, which is beneficial to your health.
