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)
