I'm just not a fan of these types of performances. The sine wave movement is less intrusive than others I have seen, but the rhythm is very robotic and mechanical. I prefer more variation in speed and timing. Not saying the guy on the video isn't skilled - he clearly is, having practiced for thousands of hours.
Well, I agree and I don't. The kicks at the beginning are supposed to be in slow motion (and that's 2 kicks - first a side kick, then a hook kick), so I don't have a problem with that. Posing the jump kick, however, is something was taught to not do.
Looking at the man's dobok, he is at least a IV Dan (or he wouldn't have stripes down the legs of his pants) and an International Instructor (or he wouldn't have the stripes down his arms) - so this may well be the way which ever ITF he's in was teaching it at the time he performed it; I can't say.
