$19 for a Five-Class Pass at Spiritworks Yoga ($39 Value)

From Napoleon's great crab walk through Europe to J. Robert Oppenheimer's discovery of nuclear fission by kissing his own elbow, victory has always gone to the most flexible. Overpower enemies with today's Groupon: for $19, you get a five-class pass at Spiritworks Yoga in Forest Hills (a $39 value).

Spiritworks' Yoga Studio affords yogis and yoginis of all skill levels the chance to increase flexibility and develop mind-body balance in an intimate, bamboo-floored studio. Typically housing 10 or fewer participants, classes take place several times a day and last for 50 - 90 minutes. Try intro to yoga, where students develop traditional asana poses, or amp up for power flow, a more demanding, faster-flowing class focused on building strength and cardiovascular endurance. Beginner, intermediate, and advances classes are all taught by Spiritworks' limber-minded instructors, who, when combined, account for more than 20 years of fitness experience and at least one half of a complete Captain Planet.
