Ms. Olympia is a professional female bodybuilding contest organised by the International Federation of BodyBuilders. It was first held in 1980, and since 2000 it has been held at the same time as the Mr. Olympia contest as part of the "Olympia Weekend". The 2000 contest also saw the introduction of weight classes. No overall winner was named in 2000, but starting in 2001, a posedown between the two class winners decided the overall title. In 2005, the contest returned to the one open class format. The top all time winners are Lenda Murray (eight), Cory Everson (six), and Kim Chizevsky (four).
