According to the principle of regulating the body's biological clock, the body's adaptability and physical exertion are best in the afternoon and near the evening (about 4 to 6 o'clock). At this time, most people are calm and stable, full of physical strength, and the flexibility, coordination, accuracy and adaptability of technical activities are at their best, so running at this time is also a very good choice.

Maybe you feel more active in the morning, in the best condition in the morning, and willing to exercise, but have you ever thought that you still have a whole day to do and you need more energy to deal with the affairs of the day? Ironically, morning exercise has one of the biggest advantages over afternoon exercise: it is easy for people to stick to it. Because there will be no conflict in the exercise schedule at this time, people will not be distracted by other things. Persistence is a very important influencing factor of exercise.

However, no matter what time you choose, you should follow the following suggestions to make your exercise more effective and interesting.

From 9 am to 10, the air is fresh and the oxygen content is high. The peak level of adrenocortical hormone in the body can mobilize all organs of the body to play their roles effectively, and the state of the body is relatively good, so you will feel focused, energetic and full of passion. The most important thing is that during this period, between meals, exercise has the least adverse effect on the digestive system. Because whether you run after a meal or eat immediately after running, the sympathetic nerve is in an excited state, which inhibits the secretion of digestive juice, slows down gastrointestinal peristalsis, affects the digestion and absorption of food, and will lead to stomach problems over time.
