Guys, this is an old post, but I wanted to revive it as I think it's really worth going to Russia for MMA training. As I am doing combat sambo (which is basically mma), I was looking at some of the options where I could go for a few weeks during summer just to train the whole time I am there from early in the morning until night every day during the stay. It will be different for people in the US, but if you are around Europe/Asia, then you should definitely go to Russia.
The three destinations I had in mind were Netherlands (because of all the kickboxing gyms), Thailand (obviously), and Russia. The gyms in Netherlands are cheap and the flight is cheap, but accommodation and living is expensive. Then, for Thailand the plane ticket by itself is like 500 bucks which is a no-no. With Russia, though, flying is cheap, gyms are cheap and accommodation is cheap. Here is my rough estimate for 3 weeks that I planned for myself around May 2019
-Plane ticket from Turkey to Russia and back: 250 bucks
-Accomodation: a private room from AIRBNB: about 15 bucks per night - 315 dollars
-Training: I am not sure but no more than 100 dollars
-Food: No more than 300 dollars

that is roughly 950 dollars for 21 days
Ukraine will also cost around the same but Russia has much better training.
