THE CORE KNOWLEDGE

Understanding Ki Bohn Soo

Begin with the overview, training purpose and deeper meaning before exploring the five wider perspectives.

Overview

Ki Bohn Soo is a set of 15 fundamental techniques within the HGMS 1st Dahn curriculum.

The set develops foundational movement, balance, circular redirection, joint control and automatic response. It places particular emphasis on the principle of YOU-WON-HWA and on learning the underlying movement patterns deeply enough that they become natural rather than remaining consciously remembered sequences.

Core Principle: YOU-WON-HWA

YOU represents softness or fluid-like movement.

WON represents circular or circle-based movement.

HWA represents togetherness, harmony or moving in unison.

Together, these ideas encourage the practitioner to move smoothly with incoming force, redirect it through circular motion and lead that movement into control rather than relying only on direct resistance.

Training Purpose

Ki Bohn Soo is foundation-level training. The priority is to develop the basic movement patterns until they become increasingly automatic.

Training emphasises fluid movement, circular motion, balance, stability, coordinated movement, repetition, spontaneous response, adaptability and control.

Through repeated practice, the practitioner begins to develop a feel for joint locking, throwing, pressure-point application and controlling movement.

Training Method

The techniques should not be approached simply as 15 fixed movements to memorise. Their value comes from repeated practice of the underlying principles.

As the movements become more familiar, the practitioner should begin to respond with less conscious hesitation and greater spontaneity.

Over time, the aim is to move from deliberate execution towards increasingly natural and adaptable response.

Deeper Meaning

Ki Bohn Soo is not simply a collection of 15 techniques. Its deeper purpose is to establish a way of moving.

Through softness, circular movement, balance, repetition and coordinated response, the practitioner gradually reduces unnecessary tension and conscious hesitation.

Repeated training allows technical movement to become increasingly natural. This creates a foundation from which later locks, throws, controls and more advanced applications can develop.

Ki Bohn Soo therefore begins the transition from remembering techniques to understanding movement.

What the learner should take away

Ki Bohn Soo teaches that technique is not only about strength, movement can redirect rather than simply oppose, balance matters throughout application, repetition develops automatic response, control matters more than forcing a technique, and the principles behind the movements matter beyond the individual techniques.

YOU-WON-HWA provides an important framework for understanding how the set moves.

FIVE AREAS OF UNDERSTANDING

Look beyond the technique.

Discover how each of the five HGMS areas gives another way to understand this Knowledge. A perspective is shown as published only when material is available.

Martial Arts

Korean in nature

Ki Bohn Soo develops important martial foundations.

The set trains balance, circular movement, coordination, joint control and disciplined repetition. Rather than treating each technique only as an isolated movement, the practitioner develops patterns that support later technical growth across the wider art.

The emphasis on fluidity, balance and automatic response makes Ki Bohn Soo an important foundation for more advanced technique.

Combat Arts

Modern application

Ki Bohn Soo introduces the practitioner to the idea of receiving and redirecting force rather than relying only on direct opposition.

The set develops foundational methods of joint control, throwing, pressure-point application, movement control and adaptation to incoming force.

Repeated practice helps the practitioner become more comfortable responding through movement, redirection and control. The combat value lies not simply in reproducing the set, but in developing principles that can later be adapted.

Philosophy

Meaning and deeper understanding

Ki Bohn Soo expresses YOU-WON-HWA through movement.

Softness does not mean weakness. Circularity does not mean avoidance. Harmony does not mean passivity.

Together, these ideas encourage the practitioner to work with movement rather than simply oppose it. Force can be received, redirected and transformed into control.

This makes Ki Bohn Soo more than a collection of techniques. It begins to teach a way of responding.

Medical Knowledge

Anatomy, health and safe practice

Ki Bohn Soo includes joint control and pressure-point application.

Because these methods act directly on another person's body, precision and control are important throughout practice.

Further updates are coming to this section.

Scientific Knowledge

Biomechanics, forces and evidence

Ki Bohn Soo develops the use of circular movement to redirect incoming force.

Rather than always applying force directly against force, the practitioner learns to change the direction of movement and use that redirection to create control.

The key scientific ideas currently represented are direction of force, redirection of movement, stability, balance, movement efficiency and circular pathways.
