When I first heard about CityStretch, a new guidebook to NYC yoga, I had a total V8, I-should-have-thought-of-that moment. We have guides to just about every possible niche here--from restaurants to nightlife to erotica shops. And now, there's yoga.

Though I haven't gotten my paws on one yet, one of the authors is a friend of a friend. Just released by a pair of New York yoginis, the book includes a comprehensive array of yoga studios. Each description has price of classes, style, level, rating, and a chatty review. There's also a handy icon guide to amenities like showers, bottled water, secure storage and towels. Some reviews have a sketch of a hand in gyan mudra to denote "top picks" that are "worth the schlep." (You can see sample pages here.)

It definitely appears that this is a very "scalable" (oy, one too many marketing conversations this week) concept that could spread to any city. The real "value-add" (aak, I can't stop!) here is that the guide includes coupons to classes worth more than $450 at studios that include: Yoga Works Westside, Yoga Center of Brooklyn, Golden Bridge, The Breathing Project and the Chopra Spa.

All seemingly worth the $15 cost of the book, which you can only pick up at the CityStretch website right now.

I'm planning to order one. Will you let me know if you do? Would love to have reviews of the reviews.
