Like fish or itinerant biology professors, yoga comes from many different schools. Give spines a flexible education with today's Groupon: for $25, you get 10 classes at The Yogi Tree in Toluca Lake (a $120 value).

Within The Yogi Tree's orange-hued interior, deep-breathing bodies follow instructors' poses in classes open to all ages and skill levels. Flex vocal cords and tendons in the Kundalini yoga class, which works sound currents and breathing passages along with external movements, drawing on a 5,000-year-old tradition that allowed ancient news anchors to shout breaking updates for thousands of miles. Qi gong classes seek to synchronize circulatory systems with movement and breath, and the musically scored motions of the Hatha yoga class focus on balancing the body's natural opposing energies, such as hot and cold or butter and peanut butter. Lunchtime yoga classes add flexibility to the most rigid schedules, providing a low-calorie snack and an hour of Kundalini-based yoga exercises to purge midday slumps. Prenatal classes keep bodies spry through pregnancy, and kids' and teen yoga courses keep youngsters nimble and teach them how the shapes in their geometry textbook really feel.

The Yogi Tree soothes parched throats with complimentary water and tea, and provides full changing facilities and free mats. After 4 p.m. Sunday Kundalini yoga classes, the group relaxes and enjoys a complimentary yogi-style dinner, discussing the intricate patterns on nearby tapestries and debating the intricate screenplay of The Langoliers.
