After 17 years as a professional fighter and nine titles, kickboxing and karate champion Brian Schwartz stepped out of retirement to try his fists at MMA. A broken hand and, subsequently, the first professional loss of his career slowed him down, but not for long—the next year, he returned to face and beat that opponent. Naturally enough for a man who can’t let a new challenge go untested, Schwartz then turned his focus to a new endeavor: the creation of Undisputed Boxing Gym, where he would share the secrets of the fight with a new generation.

Schwartz has assembled a dynamic staff of fighters with backgrounds in jujitsu, boxing, tae kwon do, and kickboxing to train both aspiring fighters and average fitness enthusiasts. Students can tone up and learn self-defense techniques or even chase a spot in the gym's amateur competitive program. The sweat flows in expansive training facilities that include a tae kwon do dojo, a cycling studio, a set of 40 Everlast heavy bags, and displays that track class progress as well as show the music videos for the songs being played. An in-house chiropractor helps align muscles and massages away any knots from learning an especially brutal tickle submission.
