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 $30, you get a 10-class pass at Regeneration Fitness ($80 value).
Owned and operated by fitness consultant Kathleen Rea, Regeneration offers yoga, Pilates, yogalates, and cardio sculpt classes for keeping the body as close to its factory settings as possible. The yogalates class is the result of cross-breeding yoga and Pilates, both of which are also offered as separate classes, and is designed to maximize the body's muscle tone, improve its flexibility, and pour a fresh batch of strength into its core. During the cardio sculpt class, light weights and resistance training help tone bodies while increasing the odds of out-swimming an angry hippo. Walk-ins are welcome, but calling ahead is preferred.
