Results: according to the magnitude of the degree of influence, users’ per-ceived benefits affecting stimulation factors include acquiring fitness knowledge, economic convenience, social com-munication and body exercise; users’ perceived risks affecting health care factors include product and service quality, after-sales service, corporate reputation as well as safety and privacy. In addition, from the perspective of path coeffi-cient, stimulation factors can increase users’ perceived benefits, produce a positive effect on their usage willingness; health care factors can appropriately alleviate users’ perceived risks; stimulation factors’ influence on usage willingness is greater than health care factors’ influence. Suggestions: strengthen core business sector construction; provide appro-priate economic stimulation; form the users’ sense of community belonging; build a good knowledge and culture at-mosphere; establish clear, effective, concise and easy to understand safety and privacy policies; improve product and service quality; enhance corporate reputation; improve after-sales service.
