A martial art is a combat sport that requires you to use your body to defeat your opponent. It is based on punches, strikes, and kicks to deliver pain and gain control of your opponent. Judo is the most popular martial art in the world and it is known as the "the king of all martial arts". It is considered to be the sport of athletes and not warriors.
