When there are activities in the gym, the coach will ask me if I want to continue my class. When the performance is not generally poor, he hardly urges orders. Because I have always been very self-disciplined, he mostly encourages me and praises me. He often takes photos of himself in the gym as an example for us, and he doesn't talk so much nonsense in class at ordinary times. I especially hate people with bad mouths. I think this kind of coach is quite good. If you have money, continue to attend classes, and if you don't have money, just tell him.
