Sport treiben: Hochschulsport

Last night I finally went to the Hochschulsportzentrum .  It's basically a complex of buildings where they offer classes and exercise equipment for students - kind of like an on-campus gym, but it's a little further away, and if I read it correctly, in order to actually use gym equipment, and not just take classes, you have to pay a fee monthly or per use fee.  But then the equipment room, both weights and cardio equipment, is also where they have the climbing wall and the Vibrationstraining (which I suspect is one of those machines with a vibrating plate that you stand on, but I'm not sure what else you do).
