 Sprint star Su Bingtian heeded the call as well. The Chinese veteran, who made history at Tokyo 2020 when he became the first Asian athlete to reach the Olympic 100 meters final for 89 years, performed 10 seconds of high knees at a blistering pace. Even at 32 years of age, he shows little sign of slowing down.

 Short track speed skater Wu Dajing demonstrated some simple ways to keep active if cooped up at home. The PyeongChang and Beijing Winter Olympic gold medalist did a series of half squats, spotlighting the fact that exercising just a few minutes a day can still make a huge difference.
