Aikido techniques are designed to control attacks without inflicting unnecessary harm.

Aikidoists do not fight. Overcoming fighting reflexes is very important, as Aikido techniques rely on a calm mind, relaxed body, and accurate positioning rather than strength. 

Techniques are created from the attacker's own energy and momentum. Circular movements are used to redirect this energy

From a few basic joint locks and throws, thousands of variations provide a comprehensive defense.
