Secret Sauce Curriculum

Our 10 class curriculum features essential techniques, organized in a way that accelerates learning and removes randomness. Our proprietary system of sparring will get you sweating, but safely.

Starting jiu jitsu with a group full of more experienced people is not fun. Normally it leads to someone trying to make you their lunch or you just feel out of your depth. At Legion your day 1 starts on the same date.

I love this place.

My family is learning so much. By far the best martial arts gym I’ve ever been to. The staff is incredible and the coaches are so knowledgeable. . .

Absolutely incredible gym.

Some of the best instructors in the world. They are very welcoming from the moment you walk in. Regardless of skill level this is a good fit for Day 1 beginners or people with years . . .

Victor Diaz - Google

A unique style.

There is no intimidation walking into this gym. Everyone is smiling, welcoming and willing to guide you. The beginners class in particular is more than you could ask for!.. . .

Emily DeLeon - Google

5 week beginner course.

All the coaches are very clear and detailed on how they teach each technique. I did not think that I would learn this much in such short amount of time. . . .
