Running in the gym is different from running in the morning. Morning running is usually on the roadside or in the park. You must get up early to run. The advantage of running in the morning is that you can save a lot of money if there is some fresh air in the park. Morning running also has its disadvantages. If it is on the side of the road, there will be a lot of dust! Especially in big cities, the air quality itself is not very good! Nowadays, there are many cars on the road, and the exhaust of cars alone is particularly harmful to people, and it is the most unacceptable for many people to get up early in the morning, especially in cities, where they like to spend the night. It must be very difficult for them to get up early!
