“Hips are the very centre of aikido. Almost all the stability of a human body is based upon those joints. The way they are, the way they live and how elastic they are and what range of movement they have, are the main factors of fluent and harmonic movement and general fitness.
All aikido techniques are based upon hips… The ability to use it in a correct way is one of the secrets of aiki. To apply them well, to use them in an ergonomic way – conscious control over the pelvic region is required.”
