Today, with the popularity of intelligent wearable devices and the acceleration of the digitization process in the fitness industry, colorful online fitness activities attract more and more people to participate, increasingly becoming a part of people's daily lives. As an important complementary form of offline sports, online fitness has the characteristics of flexible venues, low threshold, and rich types of activities, which can better meet the needs of people to use fragmented time to exercise. At the same time, the application of technologies such as mobile internet and intelligent sensors has enhanced the interactivity and interest of online fitness, further stimulating people's enthusiasm for fitness. According to data released by the General Administration of Sport of the People's Republic of China, in 2022, the national sports system will hold online sports meetings for national fitness, with over 13.96 million participants. The vigorous development of online fitness has provided people with more fitness options, stimulated national fitness enthusiasm, led more people to develop sports habits, and enabled more people to share health and happiness. It can be said that online fitness not only contributes to national fitness, but also adds color to a better life. Behind the rise of more and more people is the deeply rooted concept of "active health". Fitness is an important part of a healthy lifestyle, which can strengthen the body and improve the quality of life. Currently, people are increasingly paying attention to the pursuit of a healthy life and are willing to spend more time on fitness activities. Active fitness has increasingly become a conscious choice for people. From learning fitness knowledge through short videos to using mobile fitness apps to record data such as running time and calories consumed, to participating in online virtual competitions, more and more people have realized through online fitness that health is a responsibility, and prevention is the most cost-effective and effective health strategy; More and more people understand that everyone is the first person responsible for their own health, and the "key" to health is in their own hands. Life lies in motion, and motion requires science. After the enthusiasm for fitness has increased, how to scientifically exercise has become another topic of concern to people. Through various online fitness platforms, users can easily obtain various fitness knowledge, choose online fitness courses independently, and receive more professional fitness guidance. During the National Fitness Online Games last year, more than 100 Olympic and world champions participated in "cloud training" with everyone through online competitions and topic interactions. Nowadays, more and more sports athletes are becoming "tutors" for home fitness on the Internet, which not only plays a demonstration role in guiding the public to scientific fitness, but also popularizes scientific fitness concepts and methods. It should also be noted that online fitness is in its infancy, and there is still much room for development and improvement. How to develop more sports scenes? How to improve the quality of fitness? How to promote better integration of online and offline? Solving these problems is not only an inherent requirement to meet the needs of the masses for fitness, but also an essential part of promoting the high-quality development of online fitness. This requires continuous innovation in relevant platforms to better meet the personalized needs of users, and also requires relevant departments to do a good job in public affairs
