Thai Boxing, Kicking (Teh)

The two most common kicks in Muay Thai are known as the teep (literally "foot jab,"), and the Teh(kick)chiang (kicking upwards in the shape of a triangle cutting under the arm and ribs) or angle kick. The Muay Thai angle kick has been widely adopted by fighters from other martial arts. The angle kick uses a rotational movement of the entire body. The angle kick is superficially similar to a karate roundhouse kick, but omits the rotation of the lower leg from the knee used in other striking martial arts like Karate or Taekwondo. The angle kick draws its power entirely from the rotational movement of the body. Many Muay Thai fighters use a counter rotation of the arms to intensify the power of this kick.If a round house kick is attempted by the opponent the Muay Thai fighter will normally block with his shin. Thai boxers are trained to always connect with the shin. While sensitive in an unconditioned practitioner, the shin is the strongest part of the leg for experienced Muay Thai fighters. The foot contains many fine bones and is much weaker. A fighter may end up hurting himself if he tries to strike with his foot or instep.

Muay Thai also includes other varieties of kicking, such as the axe kick, side kick or spinning back kick etc. These kicks are only used in bouts by some fighters. It is worth noting that a side kick is performed differently in Muay Thai than the traditional side kick of other martial arts. In Muay Thai, a side kick is executed by first raising the knee of the leg that is going to kick in order to convince the opponent that the executor is going to perform a teep or front kick. The hips are then shifted to the side to the more traditional side kick position for the kick itself. The "fake-out" almost always precedes the kick in Muay Thai technique.
