That's a good news. I have never thought Bitcoin was banned in Russia because I know many people from there using it. Although NanoFitness is not a very famous gym it is still nice of them to accept Bitcoin. We definitely need more news like this around the world.
There was a polemic about the bitcoin prohibition some time ago, but it was solved. Now that is very good news. Gyms accepting bitcoin will introduce a new public to crypto currencies, the bodybuilders and all the people going to gym.
It is useful like a marketing for bitcoins, we should thanks russians for this, they gave the first step on this.
