There is a gym in the building opposite the Smile Hall on Cross Street, which seems to be called "Evergreen Tree". The facilities are relatively complete.

There is one above the drugstore at the intersection of Jiefang West Road and Taiping Road. It's a little worse than "evergreen tree", but it's cheaper.

It's on the second floor of the badminton court over there in Jiatianxia Square. It is also more professional, and the price is similar to that of "Evergreen", which may be a little more expensive.
