How we train.
This site teaches no-gi grappling through a constraints-led, ecological approach: skill grows from solving real problems against a resisting partner. The mechanical principles, the training games, and the coaching design that ties them together are all here.
A constraints-led approach
Traditional instruction shows the shape of a technique and has you repeat it. A constraints-led approach starts from a problem: the coach sets a position, a goal for each side, and a constraint, and the grappler arrives at a solution by playing it under resistance. The solution works because of a mechanical truth — what this site calls an invariant — and the game is where a grappler learns to see it and use it. Why that mechanical truth holds — the leverage, the joint, the force — is the science, the method's twin.
You cannot learn to grapple from a page. Attunement happens on the mat, with a coach and a resisting partner. A written resource makes the parts explicit — the principles a grappler is learning to read, the games that train them, and the design behind both — so the reading supports the training and the mat does the rest.
The science
Ecological dynamics
The theory — how perception and action couple, and how a grappler self-organises a movement from what a position affords.
The constraints-led approach
How a coach builds skill by designing games — shaping the position, the goals, and the rules so a solution emerges under resistance.
Affordances and attunement
Getting better as learning to see more — what a position offers, and how a grappler tunes their perception to read it.
Focus of attention
The best-replicated cueing finding in motor learning — cue the effect, not the body part. Why external beats internal for performing and learning.
Representative learning design
Why practice only transfers when it carries the information of a real exchange — and how to narrow a task without stripping it.
Repetition without repetition
Skilled movement is never the same twice. Why varied problem-solving builds adaptable skill and rote reps build brittle ones.
Drilling and games
Where cooperative drilling earns its place and where live games carry the load — an honest, non-dogmatic read.
What the science does and doesn't say
An honest appraisal — what is well-supported, what is reasoned extension, what is still debated, and where the research runs out.
Coaching with the method
Positive, progressive grappling
The stance under the method — grapple to advance, on top and from the bottom, and the honest line between progressing and stalling.
Reverse phase progression
Cluster constraints-led games by match phase and run them finish-first — success before struggle, with built-in differentiation for mixed-ability rooms.
Designing a session
Build a session backward from the outcome — set the constraint, scale the difficulty, and adjust as solutions emerge.
Coaching kids
Games-based youth coaching — age-banded, play-first, safety-floored, and honest about what the research shows.
Games generator
Compose a constraints-led round from any focus — a real base game plus one constraint to try, ready to adapt.
The canon, read through the method
Invariants are information
The mechanical truths a technique expresses are also what a grappler learns to perceive — the honest link between the two senses of "invariant".
Games are representative practice
Each positional game is a designed problem that carries the information of a real exchange. The library is the part of the site you take to the mat.
The curriculum is scaffolding
One defensible way to sequence a year — a starting structure for a coach to adapt, with the safety floor held fixed.
The parts of the method
Invariants — the information
The mechanical truths that hold across every position. In a constraints-led approach, they are the information a grappler learns to read and act on.
Positional games — the practice
Constrained live rounds with a goal for each side, a fixed starting position, and reset rules. This is the representative practice the method runs on.
Concepts — the connective layer
The patterns that recur across positions — how techniques chain, where a position forces a choice. The structure that emerges as a grappler plays.
The curriculum — as scaffolding
A worked sequence for the first year of training — a starting structure a coach can adapt to their own room.
Where the approach comes from
How the layers work
How invariants, technique, and concepts relate, and how a grappler at each stage uses them.
