Private education is calculated according to class hours. The period varies greatly. In first-tier cities, it is not uncommon for coaches with five American certifications, such as ACSM, to have a class price of 1200, as high as 2,000. Third-and fourth-tier cities have regular coaches with national vocational qualification certification, with a class of about 500. Then the price is also related to the way of private education and the level of health clubs. In fact, this industry standard is not complete. It is possible for you to buy 50 classes, and it is not necessarily fake (this is related to the management of the gym). For example, some interns majoring in physical education go to the gym to work. If they teach you privately, it will not be calculated according to the "market price" and will be lower.
