If you are a personal trainer, you'd better go to a professional to study again. At least when members ask for your guidance, you can say so.
I suggest you go to a special coach training institution again, because I have met many students in sports schools, and few of them do their best.
Simply put, it's not to discourage you. The salary structure of the gym is: basic salary+sports hours+private teaching hours = full salary.
You can't hand in your PE class by yourself. If you don't return to private education, your chances of success in applying for a job are generally very small, unless you are a teaching assistant, but I have never seen a teaching assistant whose basic salary exceeds 1200. Think for yourself,
If it helps you, please adopt it. Thank you.
