The Punch House, Cincinnati

Alongside experienced instructors, nationally ranked heavyweight boxer Danny Calhoun not only gets students fighting fit during boxing and martial-arts courses, but helps empower them in a fun, safe, and motivating environment. Make that two environments—when The Punch House's student roster soared, Calhoun and his team opened up a second facility.

Calhoun himself 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, but all the teachers bring their own specialties and skills to the mat. Together, their combat tutelage has drawn such professional athletes as Indianapolis Colts linebacker Tyjuan Hagler and UFC champion Rich Franklin.
