The Martial art of Muay Thai has its own unique techniques. It consists of the use of nine weapons. The head, fists, elbow, knee and feet are collectively known as Na-wa arwud. But today the use of head is no longer allowed in the Muay Thai fights.
In Muay Thai small amount of grappling is used (The Clinch) for both defending and attacking purpose.
Muay Thai techniques are divided into two groups: Mae Mai or Major techniques and Luk mai or Minor techniques.
All techniques in Muay Thai use the entire body movement, rotating the hip partially or fully with every punch, kick and block. This is the reason which sets Muay Thai apart from other forms of martial art.

Punching Techniques:  ( Chok)

The judges in Muay Thai fights scores less to the fighters for the punching techniques as they are generally less effective and powerful than kicks or knee strikes.
Body punching is also used less in Muay Thai as it exposes the fighters head to the strikes of knee or elbow from the opponent.

Elbow Techniques: (Dhee Sork)

The elbow is used in seven ways in Muay Thai, horizontally, diagonal upwards, diagonal downwards, uppercut, downward, backward spinning and flying. The elbow is also used from the sides as a finishing move or to cut the opponents’ eyebrow so that he bleeds. Bleeding blocks the vision and also affects the fighter’s performance.

Kicking Techniques: (Dhe)

The most common kick in Muay Thai are Foot Jab (Theep) and the Kick (Tae), upward in the shape of a triangle targeting the ribs and arms (Chieng). This angle kick in Muay Thai has been adopted by many other forms of martial arts as it is very effective.
The round house kick is almost similar to the kicks used in karate or taekwondo. Many Muay Thai fighters also uses a counter rotation of his arms to enhance the power of his kick. A Muay Thai fighter is always taught to hit with his shin. Although the shin is very sensitive for an untrained person the shin is the strongest part of the leg than the foot as it contains fine bones and is much weaker.
