Former UFC and WWE star Ken Shamrock has been training fighters in mixed martial arts for years at his Lion's Den dojo in Reno, Nevada. In 2008 Shamrock opened a location in Scottsdale, boasting 8,000 square feet of training space, including a boxing ring, a fighting cage, and a fully equipped weight room. Shamrock handpicked the instructors for the Scottsdale location, who include Brazilian jiu-jitsu black belt Carlos Farias, UFC fighter Edwin Dewees, kick-boxing world champion Rick Roufus, and Shamrock himself. Members of the Lion's Den can receive instruction in a variety of martial arts, from Muay Thai kick-boxing and grappling to boxing and jiu-jitsu. Members can participate in classes or pay for special one-on-one instruction. Kids are welcome, too, as the dojo offers martial arts programs for "Cubs" (ages 4-8) and "Juniors" (ages 9-14).
