Is there a time limit for this exercise? There is no time limit for this exercise. You can make your own reasonable arrangements. As long as it doesn't conflict with your other jobs, there is no problem.

This sport is just running. When was this running? ! Some people run in the morning, so what are the benefits of running in the morning? It is said that a day's work lies in the morning. Running in the morning is not because the air is good, so we can breathe fresh air, right? Therefore, it is ok for us to run in the morning. When is a good time to run in the morning? I think it is more appropriate to run from 5: 30 to 8: 00, not later than 9: 00. Of course, this is also my personal suggestion, depending on you.

This kind of running is also feasible at night. Some people exercise at night. Running before or after meals doesn't make much difference. If you run before eating, you won't say that it has any effect on your health. If you run after dinner, you'd better not exercise immediately, because your stomach has just eaten and it hasn't been digested at that time. If you exercise like this, it is easy to cause stomach pain or other problems.

If you run, I think both time periods are feasible, as long as you can arrange them reasonably.
