Mixed Martial Arts is believed to be the fastest growing sport in the United States. The History Channel’s “Human Weapon,” hosted by Jason Chambers, mixed martial artist and professional fighter, and Bill Duff, a former professional football player and wrestler, travels the world to highlight various forms of martial arts.

In each episode, the two immerse themselves in the cultures that used these fighting techniques as a way to defend their communities. Among the fighting disciplines explored are Muay Thai, Eskrima, Judo, Karate and Savate.

After learning about the history and culture and training in it themselves, they take on one of the professional fighting masters in the discipline. Chambers has studied several martial arts including Brazilian Jujitsu and Jeet Kune Do (a blend of kickboxing, trapping and Brazilian Jiu-Jitsu).

“In a few short years martial arts has been revolutionized,” states Chambers. “Now we are seeing athletes that train in several arts in order to become a more efficient fighter. And I truly believe this is only the beginning, with movies like the Jason Bourne series, martial arts are getting some screen time in ways we aren’t used to. We all remember the flashy kung-fu movie days, but now we’re seeing gritty, realistic fights.”

Chambers is quickly building his own fan base.

“I’m constantly in awe as to how many people watch the show,” says Chambers. “I love getting fan mail about how the show has motivated someone to go out and train, or get back into shape.”

Fans of the show have a lot to digest with stops in Quantico, Va. to experience the U.S. Marines Martial Arts Program and France to study the combat art of Savate.

“Human Weapon” can be seen on the History Channel on Fridays at 10 p.m.
