Most people like to run in the morning ... in fact, the air quality in the morning is the worst. After a night of breathing by plants, the oxygen content is also the lowest and the dust in the air is the most. On the contrary, the air at night is the best in a day, but it seems that no one will run at night, maybe he will run to a remote location. ..

The most suitable time of the day for exercise should also include running. There are two time periods: 9- 10 and 3-4 pm. Exercise is the best at this time. The best time for running is half an hour. Don't run after meals, it's bad for your stomach. It is best to run in a way close to race walking.
