Fair warning to all. This is going to be a long post about my personal experience in Tae Kwon Do. It might explain why some snub the art, and call it ineffective.
My Goju-Ryu school fell apart, and I was left with the task of trying to find another one so I could continue my training. I never found another one. What I found instead were a massive amount of Tae Kwon Do schools. Tae Kwon Do outnumbered everything else 3-1. I shared this problem with a friend of mine. She was a neighbor hood counselor or something to that effect. I don't know what exactly her job title was but a large part of her task was working with the youth of the neighbor hood. She offered to help me find what I was looking for, and since she had a much greater ability to search around the area then me, I accepted.
However there is one crucial flaw on the topic of martial arts, and people who don't know anything about it. And that is they can't tell one from another. So when she came back to me with what she found, it wasn't Goju-Ryu, it was Tae Kwon Do. I suppose I should have expected that. By then I thought, hell I'll give it a try. I show up to observe a class, and talk to the instructor. The instructor was friendly, but his class was very underwhelming. I went on ahead, and joined up anyway. I starting training with this school the following week, and I have to say it didn't do anything to change my initial impression. The warm ups were very light cardio. Didn't even raise my pulse in the slightest. Then we went on to drills, which felt very static compared to how I did them before. There was just no energy, no trying to imagine striking an opponent, no anything. Just running through the motions with no real purpose behind any of the moves. The techniques were very similar to Goju-Ryu but had an extra element of complexity. But there was no reason behind the extra movement, and they just came off as clunky, and useless to me in comparison.
There was sparing, but we weren't allowed to ever make contact. We had to stay at least three feet away from each other. And almost every other move the other students would make was a jump kick of some sort. It was very hard to get an assessment of skill this way, but the other students were always very slow. No techniques were ever executed with any power, and the jumping kicks could be seen coming miles away. And I also highly doubted they had any sense of distance. Due to my previous experience I started off in this school as a yellow belt. And as a yellow belt, I could have walked right through every brown belt in the class. (none of the students were black belts yet).
At this time, I am also still training in Kung Fu. And one of the big parts of that was understanding the meaning behind all the movements, and techniques. So after Tae Kwon Do practice I would spend time alone trying to find some way to make all the extra movements in Tae Kwon Do useful. I came up with a few ideas, and I shared them with the instructor after class. I don't remember what I came up with, but somehow I was able to use the blocks as counters against being grabbed hold of. I demonstrated one of them using the middle block. His response was that the technique was only a middle block, and that's all that it was used for.
By now my opinion of Tae Kwon Do was starting to slide down like an avalanche. But still I decided to press on. The plan being to learn the material, and do the extra work on my own. Then my school started preparing for a local Tae Kwon Do tournament. During this time, one of my lungs collapsed (Unrelated to any training) and I had to go in for surgery. Fortunately I was able to make it out in time to go to the tournament. I wasn't able to compete, but I wanted to be there to support my peers. And this was when my opinion finally hit the bottom. Aside from a couple of the naturally athletic types, every single person there was weak, slow, and had no sense of timing. Their stances had no strength. Their kicks were slow, and had no power. Almost no one could throw a punch. It was all about scoring with the jumping kicks, which were also slow, and stiff. Needless to say, this was not what I was expecting from an art that was known for great kicks.
I was able to handle that within my own school. They were only a small group of people. But after watching over a hundred who couldn't do any better, I decided I was done. I didn't go back to that school, and for a long time I though Tae Kwon Do was just a joke. The phrase I created based on what I saw at that tournament was 'paper martial artist'. Because you could cut down a dozen of them like paper. I met several other people who trained in Tae Kwon Do, and after branching out into other arts, they came to believe pretty much the same thing I did.
In general this is why I think some people have a low opinion of Tae Kwon Do. Sure this is a problem in many other styles, but the 3-1 ratio of Tae Kwon Do over everything else made the paper martial artists in that art stand out much more.
But to be fair the day came when my beliefs would be corrected. A bunch of my Kung Fu buddies, and I were going to a friends house to spar. This friend happened to be a Tae Kwon Do guy. Upon learning that I thought he was just another wayward soul, and dismissed him completely, believing that I could just intercept all of his willy-nilly jumping kicks, and move in with a flurry of hand strikes unchallenged since he wouldn't be able to use his hands to defend himself. In retrospect I should have realized that this would be different since he had a very solid stance. But I didn't, and when I moved in on the attack, I was stopped cold by a perfect front kick that had plenty of power. Futher more he was quite able to use his hands, and completely shut down the flurry I tried to launch when I was able to get in close. My world was blown apart, and I honestly didn't know what to do against this person.
No only did he beat me, but he ended up being the best out of all of us. Over time I saw examples here, and there of just how great Tae Kwon Do could be, changing my opinions around completely.
