Pay attention to the qualifications, work experience and written agreement of private education before buying classes (whether the gym has corresponding system guarantee).

Coaches have basic qualification requirements, namely the national vocational qualification certificate. There are also certifications from foreign authorities. The certificates issued by those miscellaneous fitness colleges can only be used as reference.

The coach's work experience is actually related to his professional knowledge. What we ordinary people want to do is actually physical training, or rehabilitation+fitness training. Some men pursue bodybuilding training, and some women want to do rehabilitation+correction training ... then think about it. What do you want the coach to help you achieve?

Then you buy classes, how many classes do you want to buy, and what goals do you want to achieve. You should reach an agreement with the coach, make it clear and reach an agreement. What to do next depends on the coach.
