Hi there -- I'm staying in Prague for a good 4 months. I'm curious if there are any decent gyms (I usually like to go on the treadmill, with the occasional weight lifting)? I prefer some place to run indoors, than outdoors namely to stay safe -- but any advice really to help integrate regular exercise at CR will be helpful. My main concern is weight gain since dumplings, meat and beer seem to be quite yummy yet waist-enhancing there. Thanks!
