But for Tito Ortiz, life very nearly took a different path. Growing up in Huntington Beach, California, Ortiz spent part of his childhood living in motels and in the backs of other people's houses, as his heroin-addicted parents were forced to leave one apartment after another. By the time he was in sixth grade, he had dabbled in almost every drug available, and his early youth involved time in juvenile detention centers, a string of petty crimes, and a stint in a local gang. Then, in high school, Tito discovered wrestling -- the perfect match for this tough, streetwise, ambitious kid.

Tito made his mixed martial arts debut at UFC 13 in 1997, winning his first fight in twenty-two seconds. In 2000, he was chosen as a light heavyweight contender in UFC 25 and took the belt, successfully defending it five times in the following three years.

Tito Ortiz pulls no punches as he recounts his journey from Huntington Beach Bad Boy to UFC superstardom -- his difficult upbringing, his first marriage and struggles with fidelity, his battles with the UFC, his career highs and lows, and his current happy relationship with former porn star Jenna Jameson. An inspirational story of beating the odds, and an incredible glimpse into just what it takes to win in the world's most brutal arena, This Is Gonna Hurt is raw, frank, funny, and as fearless as its subject.
