The Aikido / Aiki JuJutsu Shin Do Goshin Kai is a style of martial art of traditional court and of Japanese origin. The origins of this discipline go back a millennium ago. It is the most influential discipline in the creation of modern Aikido in the mid-20th century. The Shin Do Goshin Kai style , used in Japan, is the result of the intense work of its founder, Sensei José Miranda , and has practitioners in different parts of the world. This style is characterized by the use of very short circular movements and very direct rectilinear movements, attacking the opponent's center line and using their own to enhance the movement. The Aiki concept is about the ability to abort an attack before it fully occurs, as well as to dominate the opponent's center of gravity. This requires mastering distance, cutting it using economic movements and neutralizing the action through imbalance and constant blows to vulnerable areas.
