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 $15, you get three classes of power yoga at Move Your Hyde Power Yoga, located in the heart of Hyde Park Square (a $42 value).

Power yoga differs from regular yoga in a few key ways, most notably its dedication to the destruction of evil through extreme muscular flexion. The wide range of class offerings ensures pliable posers of all levels can find a suitable challenge. Greenhorns can get started with a New to Yoga course, while veterans of powerful yogic posturing can up their yogame with the Power Flow 90, a 90-minute workout designed to infuse power yoga poses directly with DNA, creating the fitness version of Jurassic Park. Consult the schedule for a full lineup, and plan on arriving 5 to 10 minutes before a class is scheduled to begin. Bring a towel and water bottle to wipe away and replenish exercise tears.

The Move Your Hyde studio combines zen-inspired décor with cork floors and a minimalist design approach to provide the ideal tranquil background for practicing yoga. In keeping with the Baptiste methods for power yoga, the studio keeps the thermostat cranked to “rotisserie” during all classes. The 90-degree heat helps keep muscles limber and spry, while fending off injuries like a garlic yo-yo in Transylvania. Sweat out an old, inflexible mindset and replace it with a new, triumphantly springy body during your time at Move Your Hyde.

Yoga mat not provided. You may rent or purchase one at the studio, or bring your own.
