How about Xinzhuang Branch of Welsh Fitness Club?
Bikram yoga here is great. I think it is the best branch I have ever been to. It's hot and feels good. There is no swimming pool. I experienced a spinning bike here. An hour later, I felt as if I had been pulled out of the river. My clothes and pants are wet, but I feel great. I wanted to vent, and it worked well! Taking a bath makes me feel much more relaxed.
