Principles & Theories
Core Principles
These fundamental principles apply across all positions and techniques in BJJ.
1. Creation and Filling of Space
All movement in BJJ revolves around space management. Offensively, create space to advance position. Defensively, fill space to prevent advancement. Shrimping creates space; frames fill space.
2. Weight Distribution
Proper weight placement ensures control while maintaining base. In mount: distribute weight to prevent bridges. In guard: use weight to break posture. While passing: apply pressure without overcommitting.
3. Maintenance of Support
Always maintain connection points for continuous control — grips (never have empty hands), hooks (maintain contact with feet/legs), and pressure (constant connection through weight).
Conceptual Theories
Table Theory
Maintaining a stable platform with multiple points of contact — like a table needs all legs to be stable. In mount: knees and feet create "table legs." In guard: multiple grip points for stability.
Orbital Theory
Moving around your opponent's center of gravity in circular patterns rather than direct lines. Guard retention uses circular hip movement. Passing often requires circling around guard.
Block Theory
Using your body structure as interconnected frames rather than individual limbs. Arms and legs work together as blocking structures. Defensive structures use entire body alignment.
Molecular Theory
Body parts work as connected units rather than in isolation. When gripping, entire arm/shoulder/core engages. Attacks chain multiple "molecules" together.
Boat Theory
Rocking and tilting movements to destabilize opponents, similar to a boat on water. Sweep setups use rocking to load weight. Mount escapes employ bridging "waves."
Applying Theories Together
These theories work synergistically. In any position:
- Create stable platform (Table)
- Move in circles to retain (Orbital)
- Connect limbs as units (Molecular)
- Use frames as structures (Block)
- Rock to off-balance (Boat)
