Foundations

Martial arts class with students practicing techniques on mats; instructor assisting students in the background.

Our adult programs meet you where you are. Foundations builds the technical base every Jiu Jitsu game is built on — core techniques, key concepts, and supervised positional sparring to put it all to work. 

❋ Built on the Basics

A wide range of fundamental techniques and concepts taught in a structured, progressive way — whether you're brand new or sharpening what you already know.

❋ Technique-First Approach

Every class is built around clean mechanics and the principles behind them, so you understand why it works, not just how.

❋ Drilling with Purpose

Reps that build muscle memory and confidence, with coaching that catches the small details before they become bad habits.

❋ Supervised Positional Sparring

Test your technique in controlled scenarios — real resistance, real feedback, with the safety rails on while you learn to apply what you know.

From your first day on the mat to your sharpest roll,

our adult programs meet you where you are and push you forward.

Building on the concepts and principles from Foundations, Intermediate is where your Jiu Jitsu starts to take shape. Classes dive deeper into new positions, advanced techniques, and the chains and transitions that connect them — then put it all to the test with full live sparring rounds. This is where your game stops being theoretical and starts becoming your own.

❋  Deeper Positions

Move beyond the fundamentals into the positions, transitions, and systems that define modern Jiu Jitsu.

❋ Advanced Technique

Sharper details, smarter chains, and the kind of technical depth that turns good students into dangerous training partners.

❋ Live Sparring Rounds

Full rolls where everything you've learned gets pressure-tested — this is where your game stops being theoretical and starts being yours.

❋ Build Your Game

Find what works for your body, your style, and your goals — with coaching to help you develop a Jiu Jitsu identity that's truly your own.
