Legal analysis: as the case may be. First, analyze the cause of injury: 1. If you violate the operating rules and operate improperly, you are generally responsible for it yourself. 2. If it's a gym management problem, such as no safety warning, floor slipping, managers' mistakes in operation and untimely maintenance, it's generally the responsibility of the gym. If the injury is caused by the equipment itself, such as design problems and quality problems, both the gym and the manufacturer are responsible.

Legal basis: Article 1 198 of the Civil Code of People's Republic of China (PRC). Operators, managers or organizers of mass activities in hotels, shopping malls, banks, stations, airports, stadiums, entertainment places and other business places shall bear tort liability if they fail to fulfill their security obligations and cause damage to others. If the behavior of a third party causes damage to others, the third party shall bear the tort liability. If the campers, managers or organizers fail to fulfill their security obligations, they shall bear corresponding supplementary responsibilities. Operators, managers or organizers may claim compensation from a third party after assuming supplementary responsibilities.
