1. Scale of fitness club: The scale of fitness club is one of the important factors that affect staffing. The larger the scale, the more staff are needed, such as receptionists, fitness instructors, cleaning staff and so on.

2. Service items and facilities: Different service items and facilities need different staff to provide services, such as yoga, swimming, dancing, equipment training and other projects need professional coaches, and swimming pools, gyms, yoga rooms and other facilities need professional cleaners to maintain.

3. Passenger flow and business hours: The passenger flow and business hours of fitness clubs are also one of the factors that affect staffing. The greater the passenger flow, the more staff are needed, and the longer the business hours, the more staff are needed.
