When you arrive at the gym, there is a coach inside. The first time I went to see the boss's wife, she told me that the coach would teach you when you went in. The coach told me to run the treadmill 10 minutes first, and then do something else, but I can't do too much the first time! Because when you wake up the next day, you will feel pain all over. I just finished running the treadmill 1 more hours, and I felt whole body pain the next day.
