Renzo Gracie Colorado

Brazilian Jiu Jitsu Academy


Hello and welcome to Renzo Gracie Colorado. My name is Avi Kashub and I am the owner and head Instructor at this facility. Our goal is to teach the art of jiu-jitsu from upholding the self defense aspects as taught by grand master Helio Gracie to offering instruction in the more modern fast paced submission style grappling being practiced today. I bring 25 yrs of experience to the mat and we pride ourselves on maintaining a safe and clean training environment so that everyone and all age groups can train together with confidence and without fear of injury. Let us show you exactly what kind of potential you really have! Set up your free trial class today!


Our Kids Program

Every day in the United States, an estimated 150,000 kids miss school due to fear or intimidation of bullies. In fact, many believe that fear of bullying may be the leading cause of low self-confidence in children. Worse, statistics suggest that less than 15% of kids actually report acts of bullying. We know that most bullies are insecure and seek self-esteem normally by harassing smaller or weaker children. These negative experiences often create psychological trauma that might last a lifetime.

We integrate a strengthening and agility program along with self defense techniques to help improve coordination, balance and to develop the reflexes that will build a solid foundation in their Jiu Jitsu skills, learning through dynamic interaction using a variety of approaches that meet the various learning types of individual children, whether visual, kinesthetic or auditory. To learn more about our school set up a free introductory class.



Do a lot of women train Jiu-Jitsu?

Jiu-Jitsu almost seems like it was designed to prepare women for real life threatening situations. Our Self Defense techniques provide the knowledge and skills for any woman to escape from her attacker, whether she is on her feet or on the ground. It is unique because it does not rely exclusively on punching and kicking, as do many other forms of martial arts.

Punching and kicking do not represent an effective strategy against an assailant who is bigger, stronger and capable of hitting back. In addition, they are useless on the ground, which is where a rapist/attacker is most likely to assault a woman.

In addition to empowering women through the most effective self-defense techniques, the regular practice of Jiu-Jitsu represents one of the most complete forms of exercise. Students quickly notice an increase in flexibility, muscle strength, endurance and general well being. Register for your free trial class today!!!
