What Martial Arts legends say about Karel “Silver Fox” PRAVEC:
“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.”

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

12 time UFC World Champion, 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.”
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!
