Known by the mixed martial arts (MMA) community as the leader of the American Top Team (ATT) academy, Ricardo Libório is also widely regarded in Brazilian jiu jitsu as one of the top black belts ever produced by Master Carlson Gracie, and an all-around legend of the sport. Ricardo Liborio was the very first World Jiu Jitsu Champion in the super heavyweight division (above 100kg/221lbs) back in 1996, a division he won weighing little over 83kg (181lbs). He chose to compete at that weight for a chance to avenge his only loss on record against the much heavier Leonardo Castello Branco.
