Powerlifting is a strength sport that consists of three attempts at maximal weight on three lifts: squat, bench press, and deadlift. As in the sport of Olympic weightlifting, it involves the athlete attempting a maximal weight single lift of a barbell loaded with weight plates. Powerlifting evolved from a sport known as “odd lifts”, which followed the same three-attempt format but used a wider variety of events, akin to strongman competition. Eventually, odd lifts became standardized to the current three.
In competition, lifts may be performed equipped or un-equipped (typically referred to as ‘raw’ lifting or ‘classic’ in the IPF specifically). Equipment in this context refers to a supportive bench shirt or squat/deadlift suit or briefs. In some federations, knee wraps are permitted in the equipped but not un-equipped division; in others, they may be used in both equipped and unequipped lifting. Weight belts, knee sleeves, wrist wraps and special footwear may also be used, but are not considered when distinguishing equipped from un-equipped lifting
