As the saying goes, a day's work lies in the morning, so many people choose to exercise in the morning. In fact, this practice is not worth promoting. Because between 4 a.m. and 9 a.m., carbon dioxide refluxes and the air quality is not good. In addition, the blood viscosity of the human body is high in the morning, especially those who suffer from hypertension and cardiovascular diseases. Getting up early is very bad for the body. However, if you really only have time to exercise in the morning, you need to pay special attention. It is best to drink a glass of water before exercise to dilute the blood and reduce the viscosity. To choose a place far away from the lush trees, try to go to the leeward and sunny open areas, and exercise for about 40 minutes.

2. Afternoon: the best time to exercise in a day.

Traditionally, you should take a nap after lunch. In fact, at 2: 00 to 4: 00 in the afternoon, the human body's athletic ability reaches its peak. Moreover, at this time, the sunshine is abundant, the temperature is suitable, and the wind is small, which is the best time for exercise. It is best to exercise after lunch 1 hour, otherwise it will affect the gastrointestinal digestive function.

3. Evening: Suitable for weight loss exercise

If you want to lose weight, you'd better exercise at night. Exercise at night can help food digest faster, and will not make fat accumulate in the body. However, no matter whether the intensity is high or low, the nervous system will be in an excited state, so go to sleep after 1 hour.
