Aikido is a purely defensive martial art based on joint locks and arm pins. The techniques are extremely powerful and effective, but are intended to control your attacker, not injur them.
Aikidoka who study at Ryurei Aikido will learn how to defend themselves and others against a single attacker as well as multiple attackers, from any attack, and while standing, seated, kneeling or lying down.
Aikido is derived from the fundamentals of the samurai, and so we also study how to properly cut with a sword, use a staff, and a knife properly. These weapons techniques are for the better development of the aikido techniques and the furtherance of the study of Shinkido.
