The essence of all Aikido technique is spherical motion around a stable, energized center. Even when the direction appears to be straight forward or backward, close observations reveal the Aikidoist's movement to be circular. Some techniques may result in spectacular high-falls, others are small, deft movements to imbalance or immobilize the partner. Both kinds are achieved through precise leverage, centering, and the usage of inertia, gravity, and centrifugal and centripetal forces. Gravity, no longer a force to be overcome, serves to support and stabilize posture.
Ordinary movements appear graceful and economic.
Increased stamina, flexibility, and muscle development are natural results of continuous training, yet the techniques themselves do not depend on strength for effectiveness. Aikido can be practiced by men and women of all ages. Aikido techniques utilize and develop a person's balance, awareness, and inner strength. Students of Aikido learn to remain calm in stressful situations, find alternatives to conflict, protect themselves and others, and gain a sense of discipline and persistence. Both roles are important, refining skills of situational awareness, timing and body control.
