The Anatomy of the Throw: Kuzushi, Tsukuri, and Kake

Uchi-komi is the practice of entering a throw, but not completing it.

To understand the significance of Uchi-komi, we need to dissect the throw.

Kuzushi (off balancing), makes up 75% of the throw.

Tsukuri (fitting in), contributes 20%.

Kake (execution), completes the remaining 5%.

Uchi-komi focuses on training us in Kuzushi and Tsukuri, effectively allowing us to perform 95% of the throw in repetitive drills.


The Efficiency of Uchi-komi

Uchi-komi's power lies in its efficiency.

While nage-komi (completion) is undeniably crucial, it can be time-consuming, limiting the number of repetitions one can perform in each practice session.

Uchi-komi, on the other hand, enables us to practice numerous repetitions in a short period.

This rapid-fire repetition becomes the cornerstone for developing muscle memory.


Repetition and Muscle Memory

Repetition is not mere mechanical practice; it is the architect of muscle memory.

As we perform Uchi-komi drills repeatedly, our neural pathways encode the movements, creating an intuitive understanding of the throw.

With muscle memory comes competence, and with competence comes confidence.


Static vs. Dynamic Uchi-komi

Static Uchi-komi, performed without much movement, lays the groundwork for understanding the fundamental mechanics of a throw.

Dynamic Uchi-komi, on the other hand, introduces movement, providing insights into the principles of inertia and momentum in the execution of takedowns.

Both static and dynamic drills are crucial, each offering unique perspectives and contributing to a deeper understanding of the nuances embedded within the throw.


Uchi-komi and Grappling Drills

In many ways, Uchi-komi can be likened to grappling drills.

Just as we practice entering an armbar without completing the submission to the point of breaking the arm, Uchi-komi allows us to focus on the critical aspects of throws without executing the final takedown.

This controlled repetition enhances our understanding of the throw's subtleties while maintaining a safe training environment.

And remember, when you learn one technique you know one technique.
When you learn a concept you know a thousand techniques.

See you on the flipside. - Larry Keith
