This pass gets you into yoga classes for as little as $1.

Forget the coveted Black Card. We found the most exclusive piece of plastic in town.

Passport to Prana is the cheapest way to sample yoga classes in your city. Here's how it works: Pay $30 for a card that lets you try one class at each of all the participating studios in your hometown. Expiration dates vary, but most give you until March 2011 to test-drive classes from the likes of Pure Yoga, Exhale Spa and boutique studios. The pass is in play in eight major cities with plans to expand to eight more. (Don't live in a participating city? Click here for a free yoga podcast from Passport to Prana's co-founder, YuMee Chung.)

Five lucky Vital Juice subscribers will win a Passport to Prana. Enter the contest by inviting a friend to Vital Juice.

This plastic is fantastic.
