judo is a deadly self defence and it is a sport. I do judo and if you use it in a fight outside of the class with someone that doesnt know it you could end up seriously injuring them,or even killing them.Judo isnt just a self defence or a sport but for some people it is a way of life.Judo helps your cardio and increases strength and fitness.And if someone does start on you when you know judo you can defend yourself easily and if it is proformed right it will leave you and youoppoment safe.
