No one maximized their physical ability any better than Forrest Griffin.
Spawned by The Hardcore Gym in Athens, Georgia, Griffin burst on the global scene when he outlasted Stephen Bonnar in an unforgettable three-round war to win Season 1 of “The Ultimate Fighter” reality series in 2005. He went on to compile a 10-5 record in the Ultimate Fighting Championship—an extended run of success that saw him deliver half of his victories against former titleholders. Griffin reached the mountaintop in 2008, when he became the eighth man in history to capture the UFC light heavyweight crown.
