Aikido is both a philosophy and a physical discipline, Aikido--literally "the way of harmonious energy"--teaches non-violent conflict resolution, physical and emotional control, and social cooperation. Aikido can seem almost magical at first with attackers flying through the air or dropping in pain from what appear to be effortless movements on the part of the defender. However, it's not magic but movement that makes Aikido so effective.  Aikido techniques work through redirecting an opponent’s movement through evasive and circular motions. Even when the Aikidoist seems to be moving straight ahead or backwards, the Aikidoist's movements are in fact off the line and circular, giving the Aikidoist the opportunity to use balance, leverage and gravity against an opponent. Ultimately, it is the energy of the attack itself which brings down the attacker. Although increased stamina, flexibility and muscle development occur naturally as a result of training, strength is not necessary.  As a result, Aikido can easily be practiced by men and women of all ages. Aikido is a non-competitive martial art.  There are no tournaments or competitions.  Learning is by repetitive practice of movements and techniques with a partner.
