Inner peace is hard to come by, requiring complex negotiations between spleen and kidney. Find harmony more easily with today's Groupon: for $49, you get one month of unlimited classes at The Yoga Circle (a $130 value).

The Yoga Circle's focus on hosting classes that accommodate students of all skill levels earned the heated practice space the honor of CityVoter's Best Yoga Studio in 2009. The studio's robust selection of classes takes place amid temperatures up to 105 degrees. Instructors guide students through moves such as Hot Soul's repeated asana sequence, which establishes the fundamental alignment and breathing technique needed for continued yoga practice and Marvin Gaye–quality pipes. Kundalini sessions refocus minds on enhancing bodily energy with a combination of centering poses and mantras hummed in iambic pentameter, and core Vinyasa classes introduce deeply held stretches alongside such challenging postures as arm balances, inversions, and triple axels while instructors drift about to offer adjustments. Retreating to the on-site shower facilities after class, students can rid muscles of salty sweat before returning home to walk their pet slugs.
