Re: Gym buddy in Zurich?
Are you thinking of joining Arena225 in Tiefenbrunnen?
I'll might take out a one month subscription starting this weekend. I think it's 190CHF - a little pricey but 4 or 5 sessions a week would make it worth it.
Silhouette in Theatrestrasse could be a better option (within walking distance of Stedelhofen), but I don't know what it's like or what the monthly rate might be.
