Lethwei

Lethwei (also spelled Let Whay) is a Burmese (Myanmar) martial art which only uses the body. Besides the standard punches, elbows, etc., Lethwei also invokes head butts and raking knuckle strikes, making it an immensely dangerous martial arts form. During its formation, spectators from all parts of society would come to watch a Lethwei match, just as the Romans went to see gladiators at the Colosseum. Every fight would go until one fighter was KO d or didn t have the strength to continue.
