Objectively speaking, if you have a personal trainer to help you exercise, the effect will be very good! Because the average person's sports meeting is unscientific, the training effect of reducing fat and increasing muscle is not good! The prerequisite for private education is: 1, good coach 2, and actively cooperate with yourself! If you ask for private education, you'd better reach an agreement! For example, if you want to lose weight, he says he can help you. Through communication, he will promise you to lose weight for 8 weeks 15kg (assuming). In this case, you can say that after your active cooperation, you can't achieve the expected effect and ask for a refund of the private education fee you paid.
