Powerlifting is a strength sport. It resembles the sport of Olympic weightlifting, as both disciplines involve lifting weights in three attempts. Powerlifting evolved from a sport known as 'odd lifts' which followed the same three attempt format but used a wide variety of events akin to Strongman events. Eventually odd lifts became standardized to the three events squat, bench press, and deadlift. They can compete raw or equipped (that is, with or without certain supportive equipment).
