Taekyyon is often referred to as being similar to Taekwondo, but in fact there are many differences, not only in appearance but also in the principles of techniques as well as the methods of competition.

Taekkyon movements derive strength from the rhythmical movement and harmony of the lower body and torso, emphasizing bent knees and a limber waist. Techniques often thrust at the opponent’s face and body, or attack their legs to take them down. There is also an emphasis on pulling or pushing the opponents' legs to take them down as a defense against kicks.

In Taekkyon matches, the rules dictate that the two fighters should step one of their feet in front of the other, continuously changing stance to avoid leg attacks from the opponent. This rule creates a unique Taekkyon step and is a characteristic of sport Taekkyon.

A slight change in the application of sport Taekkyon techniques can create deadly kicks and strikes, particularly when these techniques are delivered to the opponent’s vital areas. During a match, however, hitting the vital parts is strictly prohibited. Combat-style Taekkyon is taught separately from sport Taekkyon.

Taekkyon does not rely on defensive techniques. When attacked, practitioners do not defend but rather attack the opponent in response. Practitioners are taught to measure their response to the level of the attack to avoid unnecessarily harming the attacker.

This philosophy is derived from the characteristics of Korean culture, a combined culture of the warlike northern horse-riding people and the cooperative southern agricultural people. Taekkyon contains a philosophy of living and prospering together in harmony, so that it can contribute to the peace and welfare of the human race.
