Basketball, Swimming, and Russian (Ulaanbaatar)

Hi all, I'm new to UB and am looking for a gym that has a basketball court and/or a decent pool for swimming laps. Does anyone have suggestions for either of those? Similarly, are there any expat groups that play regular pickup basketball somewhere around town? I'd love to join a weekly game if possible.

I've also been studying Russian and would love to continue doing so through either structured classes or a private tutor. Does anyone have recommendations or contacts for learning Russian?

Thanks and excited to be here,
Adam
