Aikido is a highly developed system of integrated movements. This system is based on the simple principle of circular force applied in harmony with an attacker’s movement, speed and timing.
In Aikido you go with the movement, you never fight or resist the movement; whether you are receiving (Uke) or performing (Shite) the technique. Essentially, it is the basic principle of moving in when pulled and pivoting out of the way when pushed.
Aikido seeks to redirect the force of an attack until it is no longer a threat and weakens an opponent by taking him off balance. Once an attacker has been taken off balance, their strength is gone and as a result, we may redirect the force of an attack until it is harmless.
