Alongside experienced instructors, nationally ranked heavyweight boxer Danny Calhoun not only gets students fighting fit during boxing and martial-arts courses, but helps empower women in a fun, safe, and motivating environment. Mr. Calhoun teaches students the same techniques for hand speed, footwork, and cardio endurance that he uses in his own pursuit of boxing's World Heavyweight Title. The facility's combat tutelage has drawn such professional athletes as Indianapolis Colts linebacker Tyjuan Hagler and UFC champion Rich Franklin to The Punch House's arenas. Inside the high-ceilinged gym, red walls frame the expanse of blue and black floor mats, bruised from the many ground-pound lessons during mixed-martial-arts classes. Heavy, full-length bags sway, only slightly malformed from the devastating combos students are taught to deliver.
