What is Taekwondo?

The name certainly translates as the way of the foot and the fist – the art of kicking, punching and unarmed combat.

Taekwondo is a Korean martial art focusing on head-hight kicks, jumping and spinning, and fast kicking techniques. This sport has roots in various Korean martial arts forms, stretching back over 2000 years.

Tae” intends to break or attack with the foot.

Kwon” means to break with the fist.

Do” interprets as the art or way.

Taekwondo concentrates on combining combat techniques and self-defence and is an excellent form of exercise mixed with fun as an art.

As a sport, it has over 70 million practitioners across the world. It originates from South Korea, where the world governing body, the World Taekwondo (WT), is currently based.

In Taekwondo, attacking and defensive movements, including punching, kicking and blocking techniques, and differing stances, are done in a set series and are referred to as Poomsae. These basic movements bring together all the martial art skills in a graceful yet powerful manner.

Poomsae forms are a significant part of Taekwondo’s promotion process, and practitioners must demonstrate a good understanding of the forms before progressing to the next grade.

Please check out our Taekwondo basics page for more information about the history, the five tenets, Korean terminology, primary hand and foot techniques, all Taegeuk and blackbelt poomsae and more.
