Brazilian Jiu-Jitsu (BJJ) is a martial art focusing largely on grappling and ground fighting. It focuses on the principles of leverage and proper technique to obtain dominant control on the ground and provides a greater position to resolve the conflict by using submission holds.

BJJ has been proven, when used properly, to be an effective method for dealing with bigger and stronger opponents and has become increasingly popular due in part to its great success and popularity in Mixed Martial Arts (MMA). A student can train in BJJ for self-defense, sports jiu-jitsu (and submission grappling) and mixed martial arts competition. It has found its way into the training regimen of nearly every successful martial artist worldwide.

Coming into a martial arts academy can be intimidating for the beginner student. Our goal with our Fundamentals class is to allow our students to learn jiu-jitsu by focusing on the controlled drilling of techniques without active sparring. This drilling not only promotes functional strength but facilitates weight loss and helps relieve stress.

The Fundamentals class serves as a foundation for all students of BJJ. Lessons are focused on teaching the principles of the art, including self-defense, basic techniques, and to commit the core movements of BJJ to muscle memory. Students find that they feel more and more confident in protecting themselves and their families if put into dangerous situations and feel confident as a whole in all aspects of their life.

For the student who is interested in competing in the sport, or if the student is just interested in testing his knowledge in a more practical setting, our advanced class offers world-class instruction. 8-time world champion (4-time Gi World Champion; 4-time No-Gi World Champion) Rubens “Cobrinha” Charles passes on his knowledge in a structured setting, which includes medium-intensity sparring to condition the body. Student’s coordination, flexibility, and balance significantly improve through sparring with classmates and the setting fosters team-building and cooperation.
