Yoga is one of the world's oldest forms of exercise, second only to holding the earth on your shoulders. Practice ancient athleticism with today's Groupon: for $39, you get a 10-class punch card at College Park Yoga Inc. (a $90 value).

College Park Yoga's close-knit team of instructors enlivens inventive Ashtanga and power-yoga classes with enthusiastic guidance, playful poses, and occasional sprinkles of pixie dust. The studio's flexible schedule of classes allows students to cultivate holistic wellness during weekend classes, and their TV records Saturday-morning cartoons to use for stretching practice later. Crimson walls and glossy hardwood floors envelop yogis as they bend and stretch in classes such as the 90-minute Yoga Basics, where pupils flow through fundamental postures, incorporating calming breaths to foster relaxation. For a more fast-paced workout, Beginner Power Yoga bends muscles into Rajastic yoga poses, designed to increase body heat internally, which stimulates detoxifying perspiration and guards against unwelcome advances from flirty snowmen. The studio's Power Yoga session exhilarates pupils with methodical breathing and poses that help improve spinal alignment and mind-body balance more effectively than a felt hat trimmed with levels.

Although College Park Yoga occasionally offers discounts, such as select free classes September 25–30, this Groupon is still the most flexible option available.
