After we moved to Paris, I was in search of yoga classes and the closest thing I found to a summary was from David Lebovitz, it was short and vague and originally written in 2006. He has updated it this year (2013), and done quite a lovely comprehensive job of it.
Paris, unlike San Francisco, doesn't have a yoga studio on every (other) corner, single classes start at a whopping 20€(around 26 USD), and could range from traditional Hatha (SF speak for 'Restorative') to a Vinyasa. Note, though, that I have tried a 'power yoga' class in Paris and it wasn't as tough as I remember a vigorous Vinyasa being back in SF. And, this being Paris, there are very few studios which have multiple rooms and/or locations to choose from. Now that my French is a little better, I've started to uncover the world of Yoga in Paris, so, stay tuned, while I demystify Paris yoga with reviews of the studios, the teachers, and up to date events here in the city of lights.
