BJ Penn talks getting his black belt in jiu-jitsu in just 3 years, as a part of a Ralph Gracie team

UFC Hall of Famer BJ Penn earned his Brazilian jiu-jitsu black belt in just three years under Ralph Gracie, an unprecedented achievement that included becoming the first American to win the Mundial (IBJJF World Championships).

Penn credits his rapid advancement to training “all the time” at Ralph Gracie’s notoriously hardcore gym. The training sessions consisted of 30-minute warmups followed by 45 minutes of guard passing drills, which Penn considers “one of the best drills ever for the history of the sport.”

“You really did learn the essence of the jiu-jitsu because that’s really what it is – two guys going at it. Can one guy pass, can one guy turn him over or finish it?” Penn explained in appearance on Jake Shields podcast. The format had winners stay in while new challengers rotated in.

Penn and Shields emphasized that the gym atmosphere was intense, with “animals” like Dave Camarillo and other top competitors training there. The team was considered one of the premier jiu-jitsu schools focusing on MMA at the time.

Beyond just earning the black belt quickly, Penn’s achievement of winning the Mundial championships as an American was groundbreaking. He described having to first compete in the “selectives” or qualifiers held in Brazilian gyms, which he found even more intimidating than the main tournament.

“It was more scary than the Mundial than the competition because you’re just in some gym and you come over for like a month for the training,” Penn said. “You know the people but it’s still the home gym.”

Penn’s remarkable three-year journey to black belt helped launch his legendary MMA career, where he went on to become a two-division UFC champion. His rapid mastery of jiu-jitsu set new standards for what Americans could achieve in the sport.
