I am in Zurich Wollishofen for internship only until end of october 2015 (thus 3 and half months remaining) and I would really like to go to gym. I am still a student. I could register with ASVZ students club for 300CHF/year and go to the gym in ASVZ Polyterrasse but I would prefer something cheaper and closer to Wollishofen. 300CH is certainly a great deal but since I am here only for 3 months more , it is not such a good deal for me.
The gym should be located ideally near Wollishofen or between Wollishofen and Rueschlikon (my internship is in Ruschlikon).
For me, the monthly membership would be best, or single entrance payments.
Right now I have found Pitch gym in Adliswil (http://www.pitsch-fitness.ch/
) - it is close to my workplace. But still quite expensive. And I do not know if they allow monthly subscriptions. Also now basefit.ch have a specieal offer 30CHF for 30 days to try the gym.
