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 $35, you get one month of unlimited yoga, Pilates, and fitness classes (a $150 value) at Indigo Studio.

The loft space at Indigo creates a relaxed environment for engaging in a variety of yoga-based and Pilates-based fusion classes, featuring creative and engaging choices, such as Yoga Booty Ballet, that are a bit off the beaten path. The aforementioned ballet of backsides combines cardio dance, yoga, body sculpting, and strength training, leaving participants limber and rejuvenated. Set to a contemporary, upbeat soundtrack, the Time Out Chicago–endorsed exercise amalgam works abs, glutes, and funk muscles while coating participants in a flattering sheen of burned calories and good vibes.

With today's Groupon tucked into your deal holster, you'll be able to drop into an unlimited number of these or other classes for one month. Options include the more traditional yoga and mat Pilates, as well as dance and strengthening classes for reinforcing threadbare core muscles and gyrating away worldly worries. A schedule almost as flexible as the instructors ensures that even the most hectic of lives will find room to work on their Jello puns.

Indigo Studio is the lotus-like brain baby of owner Jaclyn Jones, who teaches such classes as Core Floor & More with panache and enthusiasm. The studio supports everyone from newbies to veterans as malleable as master yogi Gumby himself.
