Judo is a grappling martial art first established in Japan. Instead of punching and kicking, judo practitioners use their opponent's movements against them. They strive to take their opponent to the ground using grappling, throws, and sweeps. They may also use chokes and joint locks to make an opponent "tap out." Competitive judo has a long tradition, and it's an Olympic sport. Readers will learn about judo's rich history, its basic moves, and how it can help students be the best they can be in the dojo as well as outside it.
