Chuck Liddell started training for his career at age 12 in Santa Barbara. He was a four-year starter on the football team at San Marcos High School, and became a Division l wrestler at Cal Poly, San Luis Obispo, graduating in 1995 with a B.A. in Business. As a graduation gift to himself, he had his iconic tattoo inked on his scalp, which reads "Koei-Kan" ("prosper with happiness"). He transitioned to mixed material arts when he earned a purple belt in Brazilian jiu-jitsu under John Lewis. Liddell made his UFC debut in 1998 with a decision victory over Noe Hernandez. He soon established his reputation as a
devastating striker with victories over Tito Ortiz, Renato Sobral and Wanderlei Silva over the next few years. On May 26, 2004, he knocked out Randy Couture in two minutes, winning the Light Heavyweight Title. Though he has had several years of intense training, he continues to use, and swear by the JACKRACK on a day to day basis. He frequently attends expos where he can showcase the JACKRACK and show others how easy it is to use and how effective minutes a day can be.
