Keumgang has always been an intriguing form to me. As the typical student works up to 1st Gup and then to 1st Dan they are at or near the peak of their physical abilities. Tae Kwon Do, regardless of style, typically is thought to use a lot of kicks. A persons journey to 1st Dan will literally require performing thousands of kicks to become proficient. Simply put, kicking is as strong an emphasis in TKD as punching is in boxing. Being a very out fighting style, kicking skills are a main focus. Of course there are many more techniques and skills a person will learn. Strikes, stances, and footwork are just a few. It takes the average student about 2 1/2 to 3 years to get to 1st Dan. Most people "peak" at 1st Dan. Some have made getting a black belt the goal. Some people respond to the incremental progression of moving through the color belts and the excitement of reaching black belt. It is the pinnacle; the where point many people truly start their MA life as a journeyman. Experienced, but knowing there is much more to learn. This is highlighted in the progressive nature of most form sets. TKD as a whole uses several different form sets. ITF, WT/Kukkiwon, MDK, and the many other offshoots use various tools to train. The two most common 1st Dan black belt forms are Batsai, and Koryo. Koryo in particular highlights classic side kicks, front kicks and crescent kicks. So again, kicking is an emphasis. Then out of the blue come Keumgang. No kicks, primarily only one stance, and no new techniques. What the heck??? Boring? Yes, to many. It seems so out of place in the progressive nature of forms. On the surface, it is more akin to a Kicho or basic form. So what is the thinking of the TKD Masters who created it and placed it as the 2nd Dan form? What is the intent of this seemingly easy form at the 2nd Dan stage? There is quite a lot of historical perspective regarding the forms name and the pattern is associated with Chinese term for mountain. So, not in historical terms (which we can get into if anyone wishes) what do you feel it the logic behind Keumgang?
