Boonhae: Hidden techniques?

Unlocking the Secrets: Boonhae in Korean Martial Arts

“How form analysis bridges tradition and practical application”

By Steven Lemner

What Is Boonhae?

In Korean martial arts, the term Boonhae (분해) may not be as widely recognized as “Hyung ” but its role is essential. In the past several years it has become a vital part of training, for both understanding and motivation to enhance Hyung performance.

Meaning “disassembly” or “deconstruction,” Boonhae refers to the analysis of martial forms to uncover the practical self-defense techniques embedded within them. It’s where choreography transforms into combat readiness. In the last several decades application has become a topic that has brought a wide range of applications.

There are no hidden/secret techniques, rather applications brought about by practitioners who have thought about its use. Each practitioner has a different view and thus creates a wide range of possible applications. However, without “testing” the application in real time and various scenarios only then could it become useful.

The Bridge Between Form and Function

Every martial artist learns forms—whether it’s poomsae in Taekwondo, hyung in Tang Soo Do, or soolgi in Hapkido. But without understanding why each movement exists, forms risk becoming nothing more than ceremonial routines. Boonhae corrects that by breaking down each movement to examine:

   •  Intent and Target: Is this motion a block, a strike, or a joint lock?

   •  Realistic Application: In what scenario would this work?

   •  Variation and Adaptation: How might this change against different attacks?

For instance, a “downward block” may actually be a release from a wrist grab, a takedown entry, or even a pressure point strike—depending on context. Boonhae helps students decode these hidden meanings.During one of our summer camps, George Manns Sa Bom Nim explained a multitude of uses of the low block to the amazement of the members. This became very inspiring for those that attended to further their thought process.

Boonhae vs. Bunkai: Similar but Distinct

Martial artists familiar with Japanese karate might recognize similarities between Boonhae and Bunkai, the analysis of kata. While conceptually aligned, Boonhae in Korean systems often leans into the fluid, circular movements and internal energy work characteristic of styles like Hapkido and traditional Soo Bahk Do / Tang Soo Do.

Why Boonhae Matters Today

In the age of Olympic and sport-based competition, Boonhae anchors the martial artist to the original purpose of the art: self-defense and survival. It teaches that:

   •   Every move has a purpose

   •   Form is more than performance

   •   Martial arts are rooted in real-world effectiveness

The time of which it is explained is determined by the outcome. Modern day situations change its use.

Additionally, to only explore combative applications is just one side of Boonhae. The understanding of its internal structure and components that relate to health.

For instructors, Boonhae deepens their teaching repertoire. For students, it brings meaning to repetition and enhances personal confidence in applying techniques under pressure. However, it’s is vital the student first understands the Hyung sequence, movements,directions and intent.

How to Practice Boonhae

To incorporate Boonhae into your martial arts training:

1 Choose a movement from your form.

2. Ask what it could mean beyond the textbook answer.

3 Experiment with a partner—apply the motion in different self-defense scenarios.

4. Record insights and variations, as there are often multiple valid interpretations.

5. Repeat with the next motion in your form.

Some schools formally teach Boonhae in higher belts, but any serious student can begin exploring these ideas under a qualified instructor’s guidance. It is important that they have accomplished a certain level of overall skill before applying Boonhae.

Conclusion: Train with Purpose

Boonhae isn’t just an intellectual exercise—it’s a return to the roots of martial practice. By engaging with it, we ensure that Korean martial arts remain practical, adaptable, and deeply meaningful. So next time you run through your hyung, pause and ask yourself: What does this really do?

That question is the first step to unlocking the hidden art within the form.
