The gym adopts a membership system, and members need to pay a certain fee to enjoy the service. This membership fee is one of the main sources of income for the gym, which is relatively stable. Many gyms provide personal coaching services, and these courses are often expensive, but they are welcomed by many consumers who pursue professional guidance.

Gyms also sell various products related to health and fitness, such as nutrition and sports equipment, which is also an important source of their profits. Some well-known gym brands can attract more consumers and achieve higher profits because of their good reputation and service.
