The charging method of the gym varies according to the region, gym facilities and service content. A common charging method is membership, that is, monthly card, season card or annual card. Members can use the gym facilities indefinitely within the validity period. Another way is to buy a certain number of fitness cards, such as 30 or 50 cards. During the validity period, cardholders can enter the gym with their cards, counting once each time. If you need professional fitness guidance, you can choose to buy a private education course, and the price depends on the qualifications of the coach, the course content and other factors.
