(Both gyms have yoga classes.)
There is another one in Du Dong that specializes in pole dancing. I don't know the exact number, but it's in Du Dong.
I am in the gym myself, and I have many activities, and the cost is acceptable. (Different events charge different fees, and those who learn dance purely are generally more expensive than those who learn dance comprehensively. )
These courses are held after work.
