There's been a fitness wave among some people in Shanghai, who've been stuck at home for weeks.
But that's appeared to have spread to other cities thanks to Taiwanese singer Liu Genghong.
Liu, who is also a fitness expert, has taken some time in quarantine to livestream exercise sessions with his wife Vivi Wang.
On video-sharing platform Douyin, the streams have pushed up Liu's followers by 10 million in just three days.
Simple moves, fast-paced rhythms and energetic coaching, some fans say Liu's workouts are great for all ages.
They've even prompted some spin-offs from students to the elderly, one group calls themselves "the Liu Genghong girls."
His livestream has also renewed an interest in a song from the early 2010s by fellow Taiwanese pop star Jay Chou.
Experts say home workouts have also grown more popular since the COVID pandemic began.
Activities such as yoga, weight lifting and aerobics have even become family bonding activities.
Some have customized their routines and equipment to what's available indoors.
But as with all workouts at the gym or outdoors, expert advice remains the same.
You have to warm up and stretch all muscles and ligaments before exercising.
The fitness craze has also prompted other celebrities to share their tips and routines, such as Olympic champion Eileen Gu.
And whether or not the Liu Genghon phenomenon is short-lived, analysts say fitness wave in China will live on for much longer.
