I'm looking for a gym with a good amount of free weights and hopefully a squat rack as well. I'm not sure what gyms over here usually charge but I was at California Fit yesterday in Geneva and they told me 750 CHF for 4 months.

I wouldnt mind a membership that allows me use only 2-3 times a week or whatever...I just need a place to work out at for 4 months that wont charge an arm and a leg.

Maybe try the Crowne Plaza, opposite the airport. I went there once, but never signed up. Looked well kitted out. It is considerably cheaper than the place you mentioned, I think.
