There is no specific running time. Office workers who have no time can run at night, and sometimes those who are used to getting up early can run in the morning. I think the running time suitable for them is good. For those who have a low running time goal, it can be set at 20 minutes first, and those who can persist after running can be extended to 30 minutes or 40 minutes, and the maximum can not exceed 1 hour. And running needs long-term persistence, and thin people are slow. You can use Jielimei to help you lose weight and use Meimei. !
