London Ki Aikido run martial arts classes in London, including children's classes for ages 7-14. Aikido is a defensive martial art based upon a philosophy of harmony rather than aggression. It doesn’t encourage children to go around punching and kicking, as the technique starts when someone else 'breaks the rules'. At the same time, as this art does not rely on size, speed or gender, if they use their bodies correctly, it is possible for children to throw adults.
