Professional wrestling throws are the application of techniques that involve lifting the opponent up and throwing or slamming him down, which makes up most of the action of professional wrestling. Some of these moves are illegal in some forms of traditional amateur wrestling because they can cause serious injury, especially in a competitive environment. They are sometimes also called "power moves", as they are meant to emphasize a wrestler's strength. Many moves are known by several different names. Professional wrestlers frequently give their "finisher" (signature moves that usually result in a win) new names that reflect their gimmick. Moves are listed under general categories whenever possible.
