Czech-American Karel “Siver Fox” Pravec has 20 years of Brazilian Jiu-Jitsu experience (since 1993). During his training at the Renzo Gracie Academy, Karel has trained with and studied under some of the highest authorities in the art including Renzo Gracie, John Danaher, Rodrigo Gracie, Daniel Gracie, Matt and Nick Serra, Ricardo Almeida & Shawn Williams. Karel is one of Georges St. Pierre’s training partners when Georges periodically visits the Renzo Gracie Academy in New York. Karel is a highly sought after instructor who has taught seminars across the United States and in Europe, coached BJJ and submission grappling on national and international level (ADCC, IBJJF, GQ and NAGA tournaments) & cornered amateur and professional MMA fighters.
After attending the 1st seminar on the East Coast given by the Gracie family (Helio, Rorion, Royler, Rickson and others), Karel was convinced of the effectiveness of Brazilian Jiu-Jitsu, which was further confirmed by the style’s success in the early mixed martial arts competitions. Karel started taking regular classes in Brazilian Jiu-Jitsu in the New York/New Jersey area when they first became available in 1993, when Craig Kukuk, the 1st American black belt in Brazilian Jiu-Jitsu moved to East Coast. Shortly after, Renzo Gracie, one of the most successful and dynamic practitioners and teachers of the art moved from Brazil to open an academy with classes in New York and New Jersey, and Karel became one of Renzo’s original students.
