Judo for BJJ: Master the Entry with Triangle Theory

Improve your BJJ standup with Judo positioning. Professor Matt Davis explains the ‘Triangle Theory’ and Uchi Komi drills to master your takedown entries at Legacy BJJ Omaha.

This guide focuses on Tsukuri (positioning), the second essential phase of any Judo throw, as taught by Professor Matt Davis at Legacy BJJ Omaha. Building on our previous guide, this lesson transitions from winning the grip fight to establishing the footwork required for a high-percentage takedown.

The Three Pillars of a Throw

As Professor Matt Davis explains, every successful Judo throw is a three-part process:

  1. Kuzushi (Off-balancing): Using your to break the opponent’s center of gravity.
  2. Tsukuri (Positioning/Entry): Moving your body into the optimal spot to execute the technique.
  3. Kake (Execution): The final application of the throw.

While Kuzushi creates the opening, Tsukuri is where you build the power and leverage needed to finish.

Developing Muscle Memory: The Uchi Komi

In Judo, the most common way to drill positioning is through Uchi Komi. These are repeated entry drills where you practice your footwork and body contact without completing the throw. The goal is to build the muscle memory required to enter “in the blink of an eye” during a live roll.

The Triangle Theory of Entry

To simplify the entry for BJJ players, Professor Davis utilizes the Triangle Theory:

  • Visualize the Base: Imagine the opponent is standing with their two feet at the base of a triangle.
  • The First Step: While maintaining your balance, bring your lead leg back and then forward to the edge of the triangle near the opponent’s opposite toes.
  • The One-Two Motion: Bring your back foot into the center of the triangle in a quick “one-two” fashion.
  • The Power Source: When that back foot hits the floor, it becomes the base and primary power source for your throw.

By centering yourself with a staggered foot inside their “triangle,” you align your center of gravity perfectly to uproot the opponent.

Connecting Grips to Positioning

Positioning does not happen in a vacuum. You must use your moves to off-balance the opponent so they align with your intended triangle entry. When your Kuzushi (off-balancing) and Tsukuri (positioning) are synchronized, the final throw becomes effortless.

Best Practices for BJJ Players

  • Stay Close: A common mistake for BJJ players is leaving too much “daylight” between their chest and the opponent’s back or chest. Your entry should result in tight body-to-body contact.
  • Bend Your Knees: Power in Judo comes from the legs. Ensure your center of gravity is lower than your opponent’s as you enter the triangle.
  • Consistent Drilling: Perform 10-20 Uchi Komi entries for every 1 full throw you execute during practice to refine your speed.
