Sun Yuping practices Shisuo exercise at Yinxiang in Nanjing, east China's Jiangsu Province, June 4, 2019. 78-year-old Sun joined a Shisuo team five years ago and gained not only a stronger body but lots of friends. Shisuo (stone lock), a stone dumbbell in the form of ancient padlock, is usually seen in the traditional Chinese workout routine. With hundreds of workout moves, Shisuo exercise can not only enhance strength, but also help people to coordinate hands, eyes and the body. Shisuo dates back to the Tang Dynasty in which soldiers first used it to build their bodies. The Shisuo exercise has a long history in Nanjing, east China's Jiangsu Province. Endearing itself to the public in recent years, Shisuo becomes a national fitness activity. Nearly 20 Shisuo teams are formed for regular activities and competitions. (Xinhua/Yang Lei)
