The TIME editorial and advertising departments were not involved in the creation of this content._ A coach from One Jump Sports trains children in stances for badminton at a residential community in Shenzhen, Guangdong province. PROVIDED TO CHINA DAILY By CAO YIN Whizzing through the streets of Beijing on his electric scooter, 24-year-old Wang Linbo has an important deadline to meet. No, he’s not one of the capital’s many food delivery drivers; he’s a physical trainer on his way to a lesson at a customer’s home. Wang is among a growing number of physical trainers being called out by Chinese parents to provide on-demand sports and fitness lessons for their children. Many parents, faced with already packed schedules, are concerned that their children are not getting enough exercise due to their own tight timetables. And so the marriage between China’s world-class digital infrastructure and on-demand services makes perfect sense in solving these parents’ concerns. Since school went back in September, Beijing Sport University graduate Wang has worked peak hours from 4 to 9 p.m., training children in skipping rope, running and fitness conditioning at their residential compounds or parks — bringing professional coaching directly to their doorsteps. “In this way, parents can save travel time to gyms, kids can exercise conveniently, and I can get a stronger sense of fulfillment from these one-to-one classes,” said Wang, a native of the Inner Mongolia autonomous region. He regards this service as a new model where certified trainers can offer mobile fitness solutions, adapting exercise routines to sidewalks, rooftops or community spaces. Wang is not alone. Xia Yun, 27, is in the same line of work in Shenzhen, Guangdong province. Since joining One Jump Sports, a sports education company, in June, he has been carrying his equipment to various communities to offer door-to-door sports classes to customers. Xia, a trained gym coach, initially thought this type of work would only be part-time. “When I realized that it provides a stable income and allows me to manage my own time, I decided to continue with it,” he said. Both Wang and Xia view what they do as a sunrise industry that they expect to develop rapidly in the coming years. According to a report by Yuboinfo.com, which specializes in market research and investment consulting, the current potential population size for youth sports training is 130 million, and the potential market size for sports consumption from this same group is approximately 235 billion yuan ($32.96 billion), indicating it is a high-growth industry. “Our original intention was to respond to the national fitness campaign, particularly by providing high-quality, convenient and inclusive sports services for young people,” said Huang Ling, the founder of One Jump Sports. While pledging to offer customers valuable and safe services, she has also called on government regulatory authorities to pay greater attention to this emerging business and strengthen their oversight, in an effort to ensure its healthy development. During the recent summer vacation, middle-schooler Wang Weining’s parents booked for him a customized exercise program, including resistance training and shuttle runs. He took the classes three times a week in his residential community in Qingjiangpu district of Huai’an, Jiangsu province. “Having a one-on-one coach provided me with more detailed guidance on movements compared to P.E. teachers in large classes. Not only have my skills improved more quickly, but my study stress has also been relieved,” he said. Weining’s mother praised the service, saying that parents need only place an order on their mobile phone, and their children can then exercise right downstairs from home. “This reduces transportation costs to and from gyms, and saves us the time of picking up and dropping off the kids, which is convenient for both the children and us,” she said. A mother surnamed Hu from Shujiang district in Taizhou, Zhejiang province, ordered a similar training program online for her 10-year-old son. “Weighing 143 pounds, he needed to lose weight,” she said. “My husband and I have to work, and have no time to take our boy to the gym, so the door-to-door service is a better choice.” For Wang Linbo, the coach from Beijing, witnessing the progress of his trainees through providing personalized sports services has given him a greater sense of fulfillment. “I used to teach large classes at a gym, with many students in each session, but after class, I couldn’t remember any of their names,” he said. “Sometimes, when some children asked me about their movements, I couldn’t specifically identify what their problems were.” However, one-on-one sports services are different. “In a one-hour session, I can thoroughly understand students’ physical conditions and athletic abilities, even their nicknames, allowing me to create a tailored exercise plan,” he said. “This approach also helps the trainees to master skills more quickly and become more confident.” There are seven other coaches like Wang Linbo at the company he works for, serving over 1,000 customers. While traveling between neighborhoods providing in-person guidance, they also develop and design more workout programs to enrich the exercise content and make the door-to-door sports services more professional.
