No, when you exercise in the gym, you often hear some technical terms. Many people who hear them for the first time don't quite understand their meaning, such as MC, PT and so on. MC stands for member and PT stands for personaltraining, which means personal trainer. The management right of the swimming pool belongs to the industrial and commercial department, not pt fitness. The swimming pool has the right to prohibit foreign private teaching, because foreign private teaching affects the normal order in the museum. If private teaching occurs in the museum, the swimming pool will also bear certain responsibilities. Therefore, for the sake of safety, some swimming pools will prohibit other coaches from coming to their own swimming pools.
