I just got an idea that I could take some ballet lessons in Moscow. It would be awesome because the Russians are known for their ballet skills and I used to do some dance myself as a teenager. Also, it seems that joining a gym would be very expensive anyway in Moscow. Here are some of the dance ideas I found:

Russian Ballet Camp: A program for adults, lasts about a week. It looks like it is for any ability level.

Moscow Irish Dance School: I would love this! It would be cool to learn more about Irish dance anyway.

Timofeeva Dance School: Ballet-oriented classes for adults available. I found this site that says these are all English-speaking dance schools.

Only 12 more days until we go to Russia!
