Nage-waza refers to a category of throwing techniques used in various martial arts, particularly in judo. These techniques involve using an opponent's balance and movement to execute throws, allowing a practitioner to take control of the situation effectively. In judo, nage-waza is divided into several subcategories, including te-waza (hand techniques), koshi-waza (hip techniques), and ashi-waza (foot techniques). Mastering these throws requires practice and an understanding of body mechanics, making them essential skills for judokas and other martial artists.
