QUESTION! Do you know of any FITNESS PLACES/GYM here in Amsterdam, where I can pay by CASH, and don't need to sign a 1-year contract or so?? I'm asking because I'm only here in A'dam for 2 months, therefore I don't even have a "Dutch credit card", and so far it seems like impossible to go to gym like this in this city. Any ideas where can I go? Thanks in advance! :-)
