"Tae" means "foot" or "to strike with the feet". "Kwon" means "hand", or "to strike with the hand". "Do" means discipline, art, or way. Hence Tae Kwon Do (foot-hand-way) means literally "the art of the feet and the hands" or "the art of kicking and punching".
Taekwondo is a Korean martial art known for its emphasis on kicking techniques, which distinguishes it from martial arts such as karate or southern styles of kung fu. The rationale is that the legs are the longest and strongest part of the body and kicking is an effective way to ward off an attacker. People of all ages enjoy the challenge of training in Taekwondo. Physically, taekwondo develops strength, speed, balance, flexibility, and stamina.
