Yoga is a much easier way to exercise both mind and body than testing Einstein's theory of relativity by racing a beam of light. Avoid a science-related sprain with today's Groupon: for $49, you get one month of unlimited classes at Padme Yoga Center (up to a $130 value).

Padme Yoga Center offers a weekly schedule of more than 25 Bhakti Power Flow classes in a serene, 85-degree studio. Sixty- to 75-minute classes take students through a sequence of poses linked with breathing to help body benders improve flexibility, increase strength, and take the place of balloon animals at birthday parties. Yogis float through sun salutations to energetic music while experienced instructors suggest posture modifications to accommodate students' individual practices in Bhakti Power Flow All Levels classes. Level 1 classes are recommended for downward facing puppies in need of mat-breaking.

The airy studio is both lively and relaxing, with soft green walls and honey-toned cork floors. Soft light fills the practice room and tall cubbies provide space for stuff-stashing. Students can slide into a limited amount of parking in Padme Yoga Center's free garage located in the back of the studio, or they can take advantage of the bike rack or the tack stand for mules.

While Padme Yoga Center does offer some discounts, this Groupon is still the best deal available.
