Aikido is a Japanese martial art developed by Morihei Ueshiba (often referred to by his title O Sensei or Great Teacher). On a purely physical level it is an art involving some throws and joint locks that are derived from Jujutsu and some throws and other techniques derived from Kenjutsu. Aikido focuses not on punching or kicking opponents, but rather on using their own energy to gain control of them or to throw them away from you. It is not a static art, but places great emphasis on motion and the dynamics of movement.

Aikido techniques can generally be divided into two categories: pressure holds, which cause momentary pain at an opponent's joints, and throws, which are primarily administered by turning an aggressor's momentum against him or her. Since joint holds can be administered in the direction of natural motion, one can subdue an assailant without the necessity of breaking limbs or causing permanent injury. Therefore, Aikido is one martial art that rejects the concept of checking violence with violence. The use of physical strength is of no particular advantage in the study of this martial art, making it ideal for men, women, and children alike.

Ki is the power achieved from a coordinated mind and body. Numerous instances have been reported where individuals have responded to extreme emergencies with extraordinary displays of strength. The incident in which a mother lifted one end of a car to free her child pinned beneath is but one example of many such amazing performances. The mother acted with her mind and body coordinated in that instance because her child's life was in danger, and in doing so, realized her true power, the power of Ki.

During class, calmness and coordination of the mind and body are taught through special Ki development exercises, Ki meditation, and Ki breathing, all of which require the understanding and application of the "rules" of the mind and body. The development of Ki enables one to act effectively not only in emergencies, but with everyday life as well, with calmness and a sense of well being.
