This is Thailand’s celebrated martial art and a lot of Thais are into it. In fact, it has gained worldwide popularity due to its level of difficulty. This is unique in a sense that you use almost all parts of your body. It is like boxing, but you use your elbows and knees. This self-defense mechanism emerged in 1932 and is still popular until now. It is already considered an official sport, with actual rules on how to play it on the ring.
