If it's yoga, there is someone in the Weibao Building above Hengkelong.

The 4th floor of Zhonglan is Supreme Yoga, and the 7th floor of/kloc-0 is Blue Sea and Blue Sky Yoga Class.

Behind the Chaoyang District Community Government Affairs Center on the west side of Guilin Road, there is Inpais Fitness.

They are all very cheap. If it is a holiday, it should be the cheapest in Hausa.
