Coaches are ordinary itinerant coaches and personal trainers, so itinerant coaches are only responsible for the equipment guidance of gymnasiums, the safety protection of members and the maintenance of public order in the stadium. Personal trainers are exclusive to you, including sparring, making training plans, arranging meals, relaxing and massaging before and after training, etc. Therefore, the charging standard is also divided into one-star-five-star coaches, and five stars are generally the level of professional bodybuilders. If there is a charge, the hourly rate in first-tier cities is 500- 1000, and that in second-tier cities is about 120-200. The price can also be negotiated. I hope my answer is helpful to you.
