NOTE: This blog was updated in July 2026 to separate
and clarify a principle versus a strategy, include all the principles of Han
Moo Kwan versus a subset, and add additional examples.
While being able to perform the techniques very well is
important, to truly master a martial art you must also understand and master the
principles behind the art form.
First let me start with the fact that Han Moo Kwan is a
self-defense martial art style. It is
designed for you to stay safe and end altercations quickly during in close
combat. Therefore, its principles are all
based on these premises. For the
purpose of what is stated below, the principles are the foundations to guide movement
and strategies are more the tactical plans for applying techniques.
I
will discuss each of the key principles and why it is important to mastering
the art form.
Close the Distance
The art form is meant to be performed in close, since it
uses the body (e.g., hands and feet) as weapons. In addition, most attackers do not know how
to fight close in, so learning to defend yourself close in puts you at the
advantage. To be effective close-in we
employ the strategy of short strikes.
Short Strikes
Short strikes are harder to see
coming and to stop. Short strikes put
you at an advantage since most people cannot fight close in. This advantage will keep you safe and end an
altercation quickly.
Be
offensive, not just defensive
All
techniques are considered offensive, even blocks. That is why we strike and block to
break. This is tied to the next
principle below but it is also a mindset.
Even when blocking, it is not deflecting, the block is attacking.
Strike
for damage to end it quickly to minimize injuries on both sides / Every
movement does damage
If
every movement causes damage, it will end an altercation quicker. And this means not only strikes and kicks,
but the transitions, turns, “in between” techniques. If you start using “preps” as another means
to do damage, that is a good start. In
addition, we employ linear strikes and
proper structural alignment as strategies.
Linear Strikes
Linear
strikes are also faster and harder to stop.
Both of these attributes are important to end an altercation
quickly.
Structural Alignment
Every technique has a proper alignment such that the
body’s skeletal and muscular system supports the technique to maximize
force. A few examples are (1) closed
fist punching arm alignment, (2) blocking arm alignment, (3) hip rotation and
leg lock in side kick, (4) leg lock in turnaway kicks, etc.
Get Off The Line
If you draw a line down the center of your body from
forehead to groin, it passes through the vulnerable and vital spots in the
body. So, it is critical to protect
those parts of your body. By getting off
the line, the intent is to no longer have the center of the body in a line with
attacker weapons.
Protect yourself at all times
If you are protecting yourself at all times, especially
vulnerable spots, you will stay safe. We
protect ourselves when we keep elbows close to the body and protect the
ribs/kidneys, or by keep weight off the front foot in cat stance to protect the
knee, or arm traveling straight up first in high block to protect the
head. If any of your techniques leave
you vulnerable for other than a fraction of a second, you may relook at how you
are performing the technique. In
addition, a key strategy is to keep proper posture and alignment so stay balanced
and use the structure of the body to maximize force, absorb the force, and
reduce injuries to self.
Proper Posture / Stances
Every stance has an alignment
that keeps you balanced – for the most part it is head over shoulders and
shoulders over hips with your mass over your center of gravity. If you are “out of square” in punches, knife
hand, etc., you can easily be pulled off-balanced or fall forward if an
attacker steps aside as you lean in to strike.
Structural Alignment
Every technique has a proper alignment such that the body’s
skeletal and muscular system supports the technique to minimize injury to
self. A few examples are (1) closed fist
punching arm alignment, (2) blocking arm alignment, (3) hip rotation and leg
lock in side kick, (4) leg lock in Turnaway kicks, etc.
Keep it simple
At its essence, Han Moo Kwan is simple and
straightforward. Certainly, there are
some exciting and fancy moves you can practice that look flashy and fun to try
and impressive to perform, but those are not always effective, require more
moves which more opportunity to be stopped and slower, or keep you safe. The goal of Han Moo Kwan is to be effective
and stay safe therefore with that objective in mind, techniques are kept
straightforward and simple.
Focus on the opponent, not just the weapon. The opponent is the one that will harm you
If an assailant has a weapon, you need to be aware and
control, trap, and disarm as focus on attacking vulnerable locations on the
assailant. If the assailant is injured,
they may no longer be able to use said weapon.
Fight as if your life depends on it, doing whatever it
takes to defend your life
As the art form is meant for self-defense purposes, IF you
have no choice but to use physical techniques, then you should continue to
fight until feel safe and / or are safe.
Be grounded at all times
By being grounded at all times, you are harder to move and if
you do move, you move in control and safely. By being grounded your techniques
come from your Center which makes your techniques more powerful.
Use Energy
When we use energy, we add even more power to our techniques. When we add the intention of inflicting severe
damage and destruction to the energy, then the techniques are near impossible
to stop. And therefore, any altercation
will end quickly.
None of these principles get mastered all at once. It takes years of practice and focus on each
one, then many at once, then all at once to master the principles. And once you master the principles, you will
master the techniques, and then you will master the art form.
