A revolution is taking place in the fitness industry. Its core consumption scenario began to extend from "venue fitness" to "home fitness". The recent popularity of "Liu Jianhong aerobics" shows people this trend intuitively. Many people did not expect that home fitness should have such a broad market. Indeed, during the epidemic prevention and control period, a large number of online demands were activated. Many life scenes that once had to go out can also be completed at home. For example, you can buy vegetables at home and work at home. Now, you can also exercise at home. The realization of new functions benefits from technological progress. Before that, people used to play videos and imitate while exercising at home. However, it is often unclear whether the specific actions are done correctly, how the actual exercise effect is, and whether it is suitable for personal special physique. With the rapid development of mobile Internet, Internet of things and artificial intelligence technology in China, it is increasingly possible to use technical solutions to meet the needs of home fitness. For example, through wearable devices, people can realize real-time monitoring of various physiological indicators of the body, and master their physical state after exercise at the first time. Behind this is the iterative upgrading of sensors and data algorithms. On intelligent hardware terminals such as intelligent fitness mirrors, AI can correct the movement posture through action recognition and other methods, and can also provide personalized suggestions for fitness courses by analyzing the movement performance of users. This can not be achieved without China's progress in computer vision, speech processing, deep learning and other fields in recent years. The improvement of user experience lies not only in technology, but also in the change of business model. For a long time, there have been many pain points in the traditional fitness industry characterized by "venue fitness". For example, when users go to the gym, they have to pay extra commuting costs. Please teach privately and buy courses. You have to pay a large amount of money at one time. However, after "getting a card", you also face a high degree of information asymmetry. You are not sure whether the coach will continue to maintain the quality of service, or even whether the gym will suddenly "roll money and run"... For gym operators, the original industry is often a "heavy asset" model: rent, store expansion, equipment maintenance, and coach wages are not small expenses. If you want to make a profit, you will naturally focus on continuous "innovation" and "renewal". However, the smart fitness industry, which focuses on home fitness, has completely thrown off the "heavy asset burden" of the past and focused on "making smart devices + selling personalized services". The commuting cost and consumption expenditure of consumers, especially female consumers who are not highly dependent on devices, will decline. Small amount and multiple content subscriptions can also reduce capital security risks. Of course, replacing labor with AI can not only avoid the trouble brought by labor, but also lose the benefits brought by labor. For example, artificial coaches can formulate and adjust training plans at any time according to users' physical characteristics, while intelligent devices and online courses cannot be so flexible. For another example, artificial coaches have irreplaceable advantages in sports safety and emotional interaction: no matter how intelligent the algorithm is, it is difficult to completely avoid the damage caused by wrong actions; No matter how strong the social attribute of the product is, it is difficult to fully convey the venue atmosphere of the gym and the one-on-one guidance and encouragement of the coach. These characteristics determine that the intelligent fitness industry and the traditional offline fitness industry will not be a substitute relationship, but a symbiotic relationship that complements and promotes each other. On the whole, China's fitness industry has a broad market. The data shows that the penetration rate of fitness crowd in China is only 21.5%, less than 1/2 of that in the United States; The per capita fitness expenditure is 2596 yuan / person, and there is huge room for improvement. At the same time, the sub track of intelligent fitness is also promising. In 2021, the national fitness plan (2021-2025) issued by the State Council clearly proposed to provide intelligent services for national fitness and support the development of emerging sports such as intelligent fitness. It is expected that enterprises interested in this area will grasp market opportunities and policy opportunities, constantly launch good products, enable industries with technology, and help health with wisdom.
