In the new era, the people's demand for fitness and health is increasingly prominent, and the national fitness activities are subtly changing the public's concept of life. In the context of the COVID-19 epidemic, the public's voice for national fitness is growing. Therefore, as a solid foundation of the national fitness system, it is particularly important to establish and improve a higher-level community fitness service system. At present, relying on the existing intelligent technology, a new generation of intelligent fitness equipment, fitness data tracking and other convenient and efficient services are constantly emerging. Under the background of "internet plus", the traditional fitness scenes are constantly being transformed and upgraded, so as to accurately identify the fitness needs of residents and provide support for building a more perfect fitness service system. However, the popularization rate of the existing community fitness intelligent service is not high, and it is still in the exploration stage, and the people's awareness and sense of acquisition are low. Therefore, an in-depth understanding of the current situation of the national fitness intelligent service system is a key step to integrate development with "internet plus" and improve the quality of fitness service.
