This gym specializes in spin classes. You join a class of riders on fixed spin bikes and pound away at the pedals to music, while an instructor goads you on. If you've never done a spin class, it's a massive workout, a major fat burner. This location also has showers. It's 150rmb for 60 minute sessions and 180rmb for 75 minute interval training sessions, discounted when you book more. Check out their website for all scheduled classes.
