fitness classes/fitness exchange (Zurich)

At home in NYC I took a ballet class, I am looking for ballet or barre method classes or pilates that will not spoil my bank account. Alternately I can do exchanges.
I can teach yoga, English and/or writing in exchange for webdesign (I desperately need someone to either tutor me in wordpress or help me fix up my website), fitness buddying (hiking, jogging, rollerblading).
Also just a fitness buddy no exchanges necessary would be fine: hiking, jogging, yoga, ballet, rollerblading, etc.
I live in Zug but can easily travel to Zurich and as a New Yorker, I prefer Zurich:)
