Chinese weightlifter Chen Lijun, who competes in the 62 kg weightclass, exercises with weights during a training session in preparation for the Rio Olympics at the Training Center of General Administration of Sports in China on July 19, 2016 in Beijing, China. Lijun won the World Championships in 2013 and 2015 and is a world record holder. China is a traditional powerhouse in weightlifting competitions at the Olympic level, and Chinese athletes have set several Olympic and world records. It is a relatively new Olympic sport for women, introduced at the 2000 Games in Sydney when China's women's team swept all four events it entered. China's weightlifting contingent features just 6 men and 4 women, the maximum quota determined by the combined team standing (by points) at the past two World Championships. It means winning a spot on China's Olympic weightlifting squad can be a more competitive test than the Olympics itself. The weightlifters typically train six days a week at the national sports training center in Beijing. China is sending its largest-ever Olympic delegation to Rio de Janeiro, with a total of 416 athletes to compete in 26 sports. (Photo by Kevin Frayer/Getty Images)
