My wife is looking for a postnatal yoga / recovery class in Zürich. We searched for some places, found http://www.familyyoga.ch/ or http://www.ataia-yoga.ch/ ; goal is to find a good teacher (english speaker but german would do also) that can help reinforcing the pelvic, lower back and abdominal musculature.

Do you have experiences with these above ? Any other places that you can recommend ?

I'd recommend nina calame's class in air yoga www.airyoga.ch
