Can you do that in Olympic TKD?
I'm going to be blatantly honest right now. TKD while in my opinion is a good art and, some of the guys I've seen from Korea are pretty bad a**. Most of the American TKD I've seen is pretty much hot garbage. It's not that the art is bad but, TKD schools in America have really found their niche and that is soccer moms. Soccer moms will spend loads of money on their kids and TKD in America focuses on that demographic. Thats why when you walk into a TKD school you're likely to see a 14 or 15 year old black belt doing wheel kicks. That is very impressive to a mother of another teen but, to most other martial artists we're not that impressed. Also in the fight community we don't think very highly of TKD simply because they mainly do point sparring.
I remember an early fight of mine, it was at a bar in NWI called Finkies they use to do NHB iron man competitions with the winner taking home something like $1000, my first fight was against a TKD black belt, I remember being nervous because it was the first time I fought a black belt under MMA rules. He landed a really good round house to my mid section but, did nothing afterward I was like ok good night then and dropped him with a left cross. The thing is if he would have trained to be a fighter I'm not saying he would of beat me, because I'm really awesome

, but it would have been a longer fight for sure.
The point that I've always stated is that it's not so much what you train, and I really believe that to be true people, it's how you train. So before you TKD people start throwing flying cresent kicks my way. Realize I said most American TKD not all. You me be a total bad a** I don't know.
Cheers and goodluck training.
