While human fitness originated by running long distances to avoid being eaten, it now dictates that we run in place in order to avoid eating. Survive with the fittest thanks to today's Groupon: for $35, you get your choice of five yoga, Zumba, Pilates, and TRX suspension-training classes at Westchester Square Physical Therapy in the Bronx (up to a $75 value). Westchester Square Physical Therapy approaches fitness from a holistic and therapeutic angle. Pilates and yoga participants can stretch and pose their way to mind-body balance on the clean floors of a sun-filled studio. Zumba dancers shimmy their way to cardiovascular vigor, and TRX suspension trainees strengthen cores and limber limbs with pulley-like resistance training. Classes are small and customized to students' abilities and desires to free-climb the Empire State Building, and parking is available free of charge. Check out the class schedule to prepare for imminent fitness.

Westchester Square Physical Therapy sometimes offers gym members and patients complementary admission to classes.
