Muay Thai literally Thai Boxing and also known as The Art of the Eight Limbs. The different styles of kickboxing in Southeast Asia are analogous to the different types of Kung Fu in China or Silat in the Malay world.

Muay Thai has a long history in Thailand and is the country's national sport. Traditional Muay Thai practiced today varies significantly from the ancient art Muay Boran and uses kicks and punches in a ring with gloves similar to those used in Western boxing. Muay Thai is referred to as "The Science of Eight Limbs", as the hands, shins, elbows, and knees are all used extensively in this art. A master practitioner of Muay Thai thus has the ability to execute strikes using eight "points of contact," as opposed to "two points" (fists) in Western boxing and "four points" (fists, feet) used in the primarily sport-oriented forms of martial arts.

In its original form, Muay Thai consisted of an arsenal of nine weapons - the head, fists, elbows, knees and feet - known collectively as na-wa arwud. Although in modern Muay Thai, both amateur and professional, headbutting an opponent is no longer allowed. Muay Thai is unique in the way it uses all parts of the body, including the elbows and knees, for both training and competitions.[6]

To strike and bind the opponent for both offensive and defensive purposes, small amounts of stand-up grappling are used: the clinch. Formal Muay Thai techniques are divided into two groups: Mae Mai or major techniques and Luk Mai or minor techniques. Muay Thai is often a fighting art of attrition, where opponents exchange blows with one another. This is certainly the case with traditional stylists in Thailand, but is a less popular form of fighting in the contemporary world fighting circuit. With the success of Muay Thai in mixed martial arts fighting, it has become the de facto martial art of choice for competitive stand-up fighters. As a result, it has evolved and incorporated much more powerful hand striking techniques used in western style boxing and the Thai style of exchanging blow for blow is no longer favorable. Note: when Muay Thai fighters compete against fighters of other styles (and if the rules permit it), they almost invariably emphasize elbow (sok) and knee (kao) techniques to gain a distinct advantage in fighting. Almost all techniques in Muay Thai use the entire body movement, rotating the hip with each kick, punch, and block. The rotation of the hips in Muay Thai techniques, and intensive focus on "core muscles" (such as abdominal muscles and surrounding muscles) is very distinctive and is what sets Muay Thai apart from other styles of martial arts.
