Grandmaster “Iron” Kim Style™

Over the centuries very few individuals have ever achieved
Grandmaster “Iron” Kim’s level of skill and ability

Many people say how good they are but the true measure of skill and ability can only be seen through demonstration. Since 1972, millions of people in the United States have benefited from Traditional Moo Doe

Demonstration of Kyung Gong Sul Bope

Over the centuries, very few individuals have been able to reach the great heights of skill and ability achieved by their most exceptional predecessors, while also being able to significantly build upon and enhance that legacy. Through consistent dedication to training, building up others, and by clearly demonstrating an extraordinary level of skill and ability–as demonstrated through his execution of the Kyong Gong Sul Bope–Grandmaster Iron Kim has solidified his legacy as a true Traditional Martial Arts ICON.

One of the many personal achievements Grandmaster “Iron” Kim has reached is the Kyong Gong Sul Bope (flying side kick). Pictured above is Grandmaster jumping from the top of a building. A corner of the roof is visible in the lower right corner of the picture (indicated with a white arrow).

Kyong Gong Sul Bope is an example of the extraordinary level of skill and ability that can be achieved through Traditional Moo Doe martial arts training, and has made Grandmaster “Iron” Kim an icon to dedicated martial artists around the world. In 1970, Grandmaster “Iron” Kim demonstrated Kyong Gong Sul Bope by jumping from the equivalent of an 11-story building. In 1972 Grandmaster “Iron” Kim again demonstrated the Kyong Gong Sul Bope movement by jumping from the equivalent of an 8-story building, landing without injury on a sloped surface below. Performing the Kyong Gong Sul Bope movement is a phenomenal feat, but more important is the tremendous internal power and strength that an individual must possess in order to demonstrate Kyong Gong Sul Bope. World-wide, throughout history, only a very small number of people have been able to acheive this ability. Grandmaster “Iron” Kim is a living example of the benefits that can be achieved through the cultivation of phenomenal Moo Doe strength.

Jump Kick – photos taken in the 1970’s

Grandmaster “Iron” Kim demonstrates a flying jump side kick by jumping straight up into the air from a standing position. Once in the air he sights the opponent, decides on the method of attack, and then concentrates power to his hands and feet to carry out the attack. From this position, the body can turn in any direction (up to 360 degrees) while having complete offensive and defensive capabilities. Only someone who has the ability to combine Kyung Gong Sul Bope and Nae Gong is capable of achieving such mastery of form in movement. Through these achievements, regardless of age, miraculous strength can be attained.

In the first photo on the left, Grandmaster “Iron” Kim is attacking down after jumping over the 6’3″ instructor.

All the following information is the result of over a quarter of a century of research into the history, legends and traditions of true Moo Doe (martial arts). This research was done by a team of higher level Oom Yung Doe – the Grandmaster “Iron” Kim Style practitioners (8th degree and higher) and has been gathered from what they understand and have personally observed. It is their desire to prevent the misunderstanding and misinterpretation of true Moo Doe and to share what they have learned and gained with all individuals interested in martial arts. They are dedicated to preserving the value of Traditional Moo Doe (martial arts) in the United States so that all others may benefit by developing to their fullest potential.

Origins of Traditional Moo Doe

This map illustrates the origin and spread of Moo Doe knowledge which began near the location of the Oom Yung (Yin Yang) symbol. During the Han and Tsu dynasties, Ship Pal Gae (18 Weapons) was developed in China and, later, spread to other regions of Asia.

Have You Ever Experienced Traditional Moo Doe?

This website is intended to educate students and other interested individuals on the meaning and value of Traditional Moo Doe (martial arts). In this country, many people are confused about martial arts. Some people think that martial arts is simple self defense and some think that it is exercise or simply a way to “get in shape.” Still others think that martial arts is a sport or contest. This is unfortunate since traditional martial arts has far more benefits to offer than merely this.

Traditional Moo Doe has developed over centuries and many generations of individuals have dedicated their lives to finding the best and most correct ways for reaching their fullest potential. This knowledge is highly prized in Asia and a school that can teach correct Moo Doe knowledge is not common nor easy to find. Here in the United States, we have only just begun to understand the depth of true Moo Doe knowledge or how to recognize true Moo Doe ability. The photographs, symbols and explanations that follow are meant to illustrate the strength of the movements and forms. For the student willing to learn and to try, history has proven that the rewards are well worth the effort. It is the extraordinary mental and physical development and the combining of the mind, body and spirit that is Moo Doe. And in truth, what can be more valuable than that type of knowledge?

Grandmaster “Iron” Kim has taught some instructors, with the position of Head National Instructor and higher, the beginning levels of Kyong Gong Sul Bope. They are now capable of jumping and landing from a 2 or 3 story building without injury.

Some higher Moo Doe practitioners throughout history have left behind pictures, paintings and drawings depicting the achievements of their movements. Over the centuries, the names of many of these individuals have been forgotten, but the movement they have left behind will be remembered by many. One of Grandmaster “Iron” Kim’s greatest and most important accomplishments is being achieved through sharing his knowledge which enables hundreds of thousands of people to benefit their daily lives.

Grandmaster “Iron” Kim hopes that others will be able to reach a level of accomplishment greater than he has achieved.

“You can borrow knowledge, but you cannot borrow your mind and body.”

  • “Oom Yung Doe has the strongest movements Ive ever seen. The professional instruction combined with the history and legends gives me confidence that Im practicing properly. I felt a remarkable difference after my first lesson and I continue to develop quickly.”
  • “What Ive found here that I couldnt find anywhere else is that the instructors dont waste my time with unnecessary conversations, but they always take time to address my questions and concerns, and to point out areas in which I can improve, they are very professional”
  • “The changes Ive seen in my condition as well as in countless other students are just remarkable. I truly believe anyone who tries Oom Yung Doe can improve their condition like I did.”
  • “When the International Level Teaching team comes into town they demonstrate incredible skills and abilities, show live weapon demonstrations, various hyung movements and self-defense techniques. Im always amazed the human body can move like that.”
  • “With the International Level system (4 levels of instruction), I get the personal day-to-day attention of my instructor and instruction from all levels up to International level 8th degree black belt.”
  • “I heard so much about the rumors of Oom Yung Doe, I had to go see for myself. I was curious to find out why and what made these schools grow. I found out once I saw the open-hand and weapons demonstrations of International Level 8th Degree black belt instructors, I thought I was watching a Shaolin or Crouching Tiger movie. I wanted to learn, feel and do it. I had 15 years of previous ordinary martial arts experience and had won many tournaments. But, after practicing Traditional Moo Doe for about 6 months, I realized that Im just a beginner in true traditional martial arts. I realize the tremendous development in my physical and mental conditions. There was truly a difference because of incredible skills and abilities in their true martial art root and the care for their students. Before I thought the public made rumors because they didnt know what they wanted, but the public knew exactly what they wanted – positive results.”
