Martial arts is an art that defends itself from the threat of human or other attacks. Broadly speaking, martial arts means any method used by humans in defending themselves from enemy attacks. Martial arts are needed in the face of unwanted conditions, such as lighting, robbery etc.
In addition to self-defense, another function of martial arts is to nourish and improve the body's metabolism. Basically, a martial arts movement is a sports movement, so by routinely practicing martial arts you will get a sense of security and a healthy body.
The origin of martial arts is actually from the first time there were humans, because indeed from the beginning humans had enemies in the form of other humans and wild animals. Wars also occur from ancient times to the present.
