The popular Facebook group “Aikido” shares well-written content about the traditional martial art, and the technical notebook.
The majority of aikido techniques have what are known as omote and ura movements.
Although there are differences according to the technique, the basic principle, for example, in countering a direct frontal attack is either to enter straight into the space occupied by the opponent, or to turn around and enter the blind spot behind the opponent to execute a technique.
The former is an omote and the latter an ura movement.
