How is the winner determined in powerlifting if two athletes achieve the same total?

Powerlifting is a strength sport that consists of three attempts at maximal weight on three lifts: Squat, Bench Press, and Deadlift. Competitions take place across the world and the sport has been growing in popularity over recent years - in part due to the rise of Crossfit and the popularity of strength training.

A competition takes place as follows: Each competitor is allowed three attempts on each lift (usually smallest w-class to heaviest). The lifter’s best valid attempt on each lift counts toward his competition total. If two or more lifters achieve the same total, the lighter lifter ranks above the heavier lifter.

Competitors are judged against other lifters of the same gender, weight class, and age.
