Bushido, like Kumdo, is the "way of the warrior." BUSHI means "warrior" and DO means "the way." The warrior class, known as the Samurai, followed codes which were almost similar to that of the Kumdo. Bushido is like Kumdo in that both adopted methods using armors and swords that were made of bamboo for practice battles. The purpose of the practice fight was to increase concentration and improve both the body and the mind.

People who choose to follow and learn the ways of the Kumdo art as well as the Bushido art must abide by many strict moral codes similar to the Ten Commandments. The spirit of the Kumdo revolves around the ideas and practices of respecting one's relatives and friends and striving for both physical and mental improvements. Kumdo is still practiced in Asia today as a way to sharpen the mind and body. It is an exercise similar to Tae-Bo or Tae-Chi.
