Our Philosophy
A Different Approach to Jiu-Jitsu
RSF is a modern grappling academy built around effective modern grappling. We Combine proven technical instruction with live, constraint-based learning to develop grapplers who understand not only how techniques work, but why they work.

Our Training Method
Technique x Problem Solving
Proven Technique
Drilling provides the technical vocabulary. Students learn reliable, battle-tested techniques and develop the mechanics necessary to execute them effectively.
Live Skill Development
Constraint-led and situational training teaches athletes to recognize opportunities, solve problems and apply those techniques against intelligent resistance.
The RSF Approach
Technique gives you solutions. Constraints teach you to find them. Resistance teaches you whether they actually work.
Neither Exists in isolation. RSF Bridges the GAP.
