If many gyms have yoga, pole dancing is not very clear. There are many kinds of dance teaching in the gym, such as yoga, pilates, jazz and so on. Every gym is different.

There is a gym upstairs.

There is also one next to Lao She's former residence.

There is also a gym upstairs in Anna next to Tianqi Construction Bank (but now it seems to have moved to the narrow road opposite Tianqi)

There seems to be a gym in the north of the city, but I don't know where it is.

Last time I read the leaflet, Southwest University also taught dance, but it was a little expensive (this seems to be aimed at majors rather than just entertainment, so it is more expensive).
