Why it is important?


BJJ students develop a deep understanding of the mechanics of the human skeletal and muscular systems. Using this knowledge they are able to subdue an attacker without causing him injury, should they so choose.

Acquiring these skills is not easy, and requires mental and physical effort on the part of the student. The rewards however, are great, and include massive improvements in stamina, strength, flexibility and mental clarity.

What's in it for me?


All of our sessions consist of a warm up, conditioning training, followed by an explanation by the instructor of a specific technique. Students then pair up with other student to practice the techniques. It is an incredible workout that will challenge and strengthen the practitioner both physically and mentally.

We Love to work and train with the best
