A korean modern (ie last 200
years) martial art created for military combat.
Unfortunately the martial art has become so popular that it has suffered from a severe case of McDojos & huge increase of the sport version over the
traditional art, 10 year old black-belts are far too common & the McDojos are everywhere. The sport version is split into two branches
WTF & ITF where the latter allows boxing methods to be employed.
Unfortunately the sport is nearly completely useless for self-defence due to its point-system emphasising high kicks over strategic attack, penalty on aggressiveness in combat & not allowing grappling/clinching which all other sport-arts allow on some level + in WTFs scenario restarts after contact.
There is then the even worse branch ATA which is scam-artists at its best, ATA isn't recognised by the Koreans as a real branch of Taekwondo & ATA refuse to compete in ITF/WTF competitions alongside charging high prices for training.
Traditional Taekwondo is like any other art, a complete system in all aspects with grappling/locks/takedowns & strikes + weapon combat.
Unfortunately it is far & few between to come across, Taekwondo is a prime example of what can potentially happen when a martial art is turned into a sport, though this hasn't been the case for many sport-arts such as Judo which is a highly effective system adapted to many police forces.
John: I started ITF Taekwondo, now if anybody tries to beat me up i'll kick them
in the faceJack: You're aware that the high kicks are in most cases NOT the best option especially where you will most likely get attacked ie alleys & crowded clubs? Let alone Taekwondo doesn't prepare you for multiple attackers & the
potential for weapons being involved OR escaping if your kick is grappled.
Oh and they also hand out belts like candy in many cases. Do the sport
if you want but don't fool yourself John into thinking it will be reliable to use fully in a fight.
