Athletes compete in a series of events at the Games, which may be various standard CrossFit workouts consisting of metabolic conditioning exercises, weightlifting, and gymnastics movements, as well as a range of activities from other sports such as swimming, road cycling and strongman. The events generally are not revealed before the Games, can include unexpected elements to challenge the athletes' readiness to compete, and they are designed to test the athletes' fitness using CrossFit's own criteria. Winners of the CrossFit Games earn cash prizes and the title of "Fittest on Earth."
