Testimonial

"I joined a large Jiu-Jitsu school and from day one felt like a punching bag." "With no clue what to do, I was immediately thrown into sparring with high level competitors - it was terrible!"

"I have since been training with Know Concept Jiu-Jitsu. (I joined one of their existing small group classes)". The training is of the highest level, but is magically tailored to exactly what I need." "In a short time, I have gotten in shape, learned some great stuff, and have never felt better."

Testimonial

"I just wanted to thank you for taking such a complex sport and breaking it down in its simplest form. Your workouts are punishing, but fun. I especially like your availability during weekdays. I have learned more about myself than anything so far. Thank you again for showing me what I am capable of." - James
