Aikido is a true budo or martial way, evolved in the historic tradition of Japanese warrior arts. O Sensei wrote that budo is a work of love, a path to overcome discord in ourselves and bring peace to the world. Thus the essence of all Aikido is spherical in motion, and ultimately, it is the energy of the attack itself which brings down the attacker. Yet philosophical discussion is rare in the dojo, or training hall. O Sensei wrote that Aikido is not mere theory but an art that we must practice.
Most training is done with a partner.
Each person works as uke , the attacker, and as nage , the receiver, and both roles are stressed. Constant repetition develops timing, proper breathing, stamina, flexibility and muscle tone, but the techniques do not depend on physical strength for effectiveness. Results are achieved through precise and unified use of physical forces such as leverage, inertia and gravity. Because of this, Aikido can be practiced by men, women and children of all ages.
