I would like to join Migros Fitness Park this month but it's no fun to torture yourself alone and Swiss people are not very approachable so I don't even enjoy being there or see it as opportunity to be around people. I know people go there to exercise not to make friends but come on! it really can be more sociable than that.
If you think of joining or are already a member or would like to give it a try first then maybe we could get in touch and meet up there sometimes? PM me if interested.
