Koo Self Defense is definitely not a traditional martial art nor a mixture of different styles of martial arts. Koo Self Defense has a different approach to training its students for health, fitness and street self defense! There are hundreds of different martial arts' styles in the world today. All of them are variations of each other except for Koo Self Defense which is not a style but was uniquely created from an out of the box approach which is from a street fighting viewpoint.All martial arts training systems have been created with artificial movements that do not even relate to the real world except for one, Koo Self Defense. Koo Self Defense offers the complete total body cardiovascular workout program (mind & body) for martial arts training, self defense, health, fitness, physical therapy, street fighting and devastating knockout power! Koo Self Defense offers the most intense and vigorous exercise program. Every student trains at their own paces according to their level of fitness and builds up. You will not find a workout like Koo Self Defense anywhere in the world!An undisputable fact, a small portion of the world's population is born naturally gifted in sports, music, arts, sciences, academics, savants and geniuses. The same principle applies to natural street fighters. These individuals have no training of any type and yet posses natural knock out powers where they will demolish their opponent in seconds with simple boxing like punches. Everyone is born with different physical and mental abilities. What we do in Koo Self Defense is to enhance an individual natural ability by increasing their power through our rigorous KSD 'hyper-aerobics' a mixture of aerobic/anaerobic and power drills executed onto focus mitts/ shields at every single class.That's what makes Koo Self Defense cardiovascular training drills so unique as to enhance these natural movements' allowing the individual to challenge their body beyond its limits (if desired) and not through the unnatural mechanical techniques as found in other styles of martial arts.The late Bruce Lee was correct in his analysis that traditional and non traditional martial arts tends to follow the same path in their training curriculum and set themselves as a STYLE which in turns becomes a rigid system of training. He stipulated that a martial art training system should be as simple as possible and to the point without any kind of mysticisms or complicated movements. As Jeet Kune Do progressed, Bruce developed a system of training that involved full contact sparring which eventually he would find that his students would suffer enormous injuries should he have continued on the same path but he closed his three schools to focus on the movies instead. Although Jeet Kune Do broke all traditional martial arts' concept, it still contained blocks, sparring, wing chun techniques and so forth. Bruce Lee's book on Jeet Kune Do is full of analysis just like traditional martial arts.Master Roger Koo created Koo Self Defense from a completely different approach. Although he was trained in various martial arts, his unique concept was to develop a training curriculum NOT A STYLE based purely on a simple premise: A Martial Art & Self Defense training system = Extreme Physical Fitness + Devastating Power This is what Koo Self Defense represents. In our daily workouts, we do not focus on techniques as such, we focus on developing every student fitness level to the highest level that each individual student set as their individual goal. Complementary to that fitness training (Koo Self Defense Kick Boxing Hyper-Aerobics) which is inbuilt in the training program is the development of devastating power ( Anaerobic - Power Drills executed onto focus mitts and shields ). Since the creation of Koo Self Defense in February 1992, it has not ceases to evolve with more challenging KSD hyper- aerobics and anaerobic drills. With the development of this SIMPLE concept of training came great amounts of health benefit as noted in this web site from students who have trained in a short period of time.The premise of all martial arts and self defense system that has been taught for hundreds of years is totally wrong. Why? Because the movements they teach such as forms (katas), blocks, punching from the hips, rotation of the fist, stances, sparring, tournaments with rules bear no resemblance to what people actually do on the streets in real life situations. This is an UNDISPUTABLE fact! This is a definite shocking statement to all martial arts' practitioners. Master Koo has been in the martial arts for more than 39 years and developed Koo Self Defense based upon many unanswered questions which came from the general public while he was in traditional martial arts.Some search engines category editors place Koo Self Defense under the wrong subcategory. Koo Self Defense is NOT Tae Kwon Do, Karate, Kung Fu, Jeet Kune Do, Judo, Kuk Sul Won, Aikido, Kempo, Choi Kwang Do etc or any Korean, Chinese or Korean martial arts. Koo Self Defense is unique and should be categorized as Sports/Martial Arts/Koo Self Defense.While other martial arts despite their different names have much of the same curriculum such as katas (forms), sparring, stances, blocks and so forth and they also look alike except for they way they execute their movements. Koo Self Defense's curriculum is totally opposite to every martial arts currently in existence! The unique blend of KSD's aerobics, flexibility and anaerobic in one single class is truly unique compared to all other workout programs in existence. This unique blend has resulted in tremendous health benefits for all of our members as you will read throughout this web site which is ranked in the top 10 for most keywords in many popular search engines.
