Karate is a martial art of Japanese origin that is all about attacks through evasive body movements and/or blocking, and counter attacks using kicks, punches and strikes. Joint locks, restraints and takedowns are also used, but to a lesser extent.
People variously practice it as a form of self-defense, a way of keeping healthy and a sport. It is also used as a method for keeping fit and healthy as it develops balance, co-ordination, aerobic fitness, strength and flexibility. In addition, (and unlike many other physical activities), it also challenges the brain and requires constant mental alertness and agility.
