Aikido techniques consist of unarmed self-defence against various armed or unarmed attacks.
The attacker is either immobilised through joint locks or thrown to a safe distance. Ukemi , or the practice of receiving, is a vital part of Aikido training, and is practised both as rolling and falling exercises and as part of regular Aikido training with a partner. Although the techniques can be very effective and powerful, and include some painful joint locks and pressure points, they are designed to work through breaking the balance of the partner, rather than damaging their body. Because of the emphasis on relaxation and the use of spherical movement instead of physical force, Aikido does not demand great physical strength or fitness. However, the natural movements of Aikido lead to a flexible and healthy body, and many people experience a pleasant feeling of well-being during and after classes.
