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. Muay Thai is an especially versatile, brutal, straightforward martial arts.
