In 1969, the ever-supple Neil Armstrong unfolded his gracefully spandex-clad leg and set a bare, ballerina-like foot on the moon. Relive this pivotal moment in history with today's Groupon. For $29, you get five anti-gravity yoga classes from Exotica in Motion, a $100 value, plus one complimentary class. You must register for classes using Exotica's online system.

This airy downtown studio currently offers hour-long classes five days a week, though the schedule will soon be expanded to accommodate a senior class and mom-with-baby variant. Blending acrobatic aerial work with yoga poses and bends, this discipline is not so much anti-gravity as it is a thoroughly polite dustup with gravity. Freed from the ceaseless pull of the mundane world by a swinglike ribbon of tough, soft fabric, your spine will stretch and unlatch, allowing you to stretch farther and deeper while holding poses longer than possible with traditional yoga. Ideal for beginners unable to touch their toes, anti-gravity yoga also retains enough depth to challenge even the most impretzeled yogi.

Since its inception, anti-gravity yoga has made appearances in acts as diverse as P!nk's recent Grammy performance and the Broadway play Nine. For a play-by-play breakdown of some of anti-gravity yoga's biggest victories, including its Super Bowl XX6I triumph over the Colts, checkout the highlight reel here.
