Karel started studying martial arts in 1986 under Master Byung Sung Cha, reaching the rank of 3rd degree black belt in the World Tae Kwon Do Federation in 1995. In the early 1990′s, while studying and teaching Tae Kwon Do, Karel expanded his martial arts knowledge by attending numerous seminars, including Muy Thai, Jeet Kun Do and Gracie Jiu-Jitsu, incorporating the techniques into his martial arts arsenal. Incorporating various martial arts in one’s training became known as mixed martial arts (MMA).

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.

Studying under Renzo Gracie and John Danaher (one of the world’s most technical instructors), Karel achieved the prestigious rank of Renzo Gracie Jiu-Jitsu Black Belt in July 2006. On June 29, 2012 Karel earned his 2nd Degree Black Belt from Renzo Gracie at the Renzo Gracie Academy in NYC and was promoted to 3rd degree Black Belt in July 2015.

Although Karel competes infrequently, he has demonstrated the success of his style (focus on submissions) by winning:

  • 1st Place – 2006 Tenth Grapplers Quest West (Master Lightweight Division) – all matches won by submission
  • 1st Place – 2007 NAGA World Championship (Advanced Director – Open Weight) – all matches won by submission, lightest competitor in the division
  • 2nd Place – 2008 Grapplers Quest U.S. Nationals (Masters – Absolute) – lightest competitor in the division
  • 3rd Place – 2008 Pan Am Championship No-Gi (Black Belt – ADULTS – Lightweight)
  • 1st Place – 2010 European Championship (Black Belt – Absolute Division – Senior 3) and 2nd place in Lightweight division
  • Karel continues to compete at the highest level (World Championships – both Gi and No-Gi) in the adult divisions into his late 40’s.

Karel has a Bachelor’s degree from State University of New York (Albany) and Master’s degree from Columbia University. The education and analytical skills have helped Karel continue growing both as a practitioner and teacher of Brazilian Jiu-Jitsu.


“One must never be entirely comfortable at what he has achieved. This is the truth behind every great Jiu-Jitsu teacher… Karel Pravec is always improving his game and his knowledge of the art… He knows that to do otherwise is to settle. I salute you my fellow Black Belt. Excellence among us, it’s a must… Our students deserve the best of us. Thank you for belonging to our tribe.
Fernando Pessoa, a great Brazilian writer once said … “The value of things is not the time they last, but the intensity with which they occur. That is why there are unforgettable moments and unique people!” Karel Pravec is among those unique people; lucky are those who learn under his tutelage.”

“Karel is one of my favourite training partners. The insights in his book are excellent to learn many techniques for advanced martial artists.”

Georges St. Pierre : 12x UFC World Champion, Considered one of the greatest MMA fighters of all time & BJJ Black Belt


“I’ve been training with Fox since I was a Blue Belt. His Jiu-Jitsu is pure efficiency and has been an instrumental part of the Tristar Gym curriculum.In his book, he not only teaches a variety of powerful techniques, but he also includes pool workouts/techniques. The pool workouts, in my opinion,hit three birds with one stone. 1st it’s therapeutic, 2nd it increases your fitness level, and 3rd it makes your technique instinctual. Drilling is the key to success, but comes at a price: it taxes the body. Fox has found a brilliant solution.”

Firas Zahabi, Renowned MMA Coach & BJJ Black Belt


“Back in the early 1990’s, Karel was one of my first training partners in the early days of the Renzo Gracie Academy. We came up the ranks together and now that we are both long time Black Belts, I frequently ask him to visit my school to teach the professional class. I cannot say enough good things about his technique and teaching methods. I highly recommend the book!”
