The essence of Aikido technique is spherical motion around a stable, energized center. As in a tornado or whirlpool, the forces created not only deflect the force of the attack, but draw the attacker into the Aikidoist's control.
Aikido is known for its graceful techniques, swift, seemingly effortless movements that fling an attacker through the air, or, by means of subtle pressure applied to joints, immobilize and control the opponent. Either effect is the result of precise timing, leverage, and the instinctive use of centrifugal and centripetal forces.
