The keynote of training is the learning and repeated practice of basic techniques. These techniques are very rational ways of overcoming strong attacks. They stress the use of the whole body as a single, co-coordinated unit to attack an opponent's weak points.
The basic body movements of Aikido make it possible to evade simultaneous attacks by groups of assailants.
The basic movements derive in part from the use of the Japanese sword, spear and similar weapons. Practice with these weapons takes the form of individual exercises and paired forms. The movements are extremely interesting, develop speed, stability and coordination, and highlight many of the principles of unarmed training.
