There are three main differences between a national fitness center and a community fitness center: 1. The organizers of fitness centers are different, and the national fitness center can only be operated by investors applying for business licenses from relevant institutions. Community fitness centers are organized and managed by community trade unions. 2. The fitness staff in the fitness center are different. The National Fitness Center can be any legal citizen, as long as it abides by the business rules and reaches a cooperation agreement with the center. Community fitness centers must be community residents and conform to the relevant regulations of community fitness centers. 3. The fitness equipment and fitness programs in the fitness center are different, and the National Fitness Center plans relevant programs according to marketing. The community mainly meets the normal fitness needs.
