Taekwondo martial art is separated into two main styles:

World Taekwondo Federation (WTF) - This is the olypics sport style. Hands are rarely used, and strikes are made mainly with the legs.

International Taekwondo Federation (ITF) - Founded by the Korean General Choi Hong-Hi. Much more similar to kick-boxing. Punches are used a lot. Since the death of the general the ITF has been divided into three different private federations; each claiming to be the original purveyor. Takwwondo practice normally involves a long warm-up and stretching session before practice. Practtioners need extreme flexibility to perform many of the kicks. Taekwondo practitioners develop great physical endurance, flexibility and speed.
