As China continues to rack up gold medals in London, Beijing's fitness centers are also enjoying golden times.

Gyms across the capital have seen a spike in new members, with many residents inspired to get in shape by Olympic heroes such as badminton ace Lin Dan.

"Although the summer is a traditional peak season for fitness clubs, the number of new members in July was higher than last year," said Zhang Wei, who works in membership registration for Hosa Fitness in the Chaoyang district of Beijing. The fitness club has 86 centers nationwide, including Shanghai and Chengdu.
