The objective for each athlete is to lift the most kilograms. Lifters are required to lie on an official bench with their head and body (including buttocks) in contact with the bench, and their legs and both heels extended throughout the complete lift. Athletes must lower the bar to his/her chest. Once the bar is motionless on the chest, he/she presses upward, straightening arms and holds the bar motionless until signaled by the referee. Athletes are given three attempts to perform each lift; their performance is assessed by three referees. Weight increases for the second and third sets must be in multiples of 2.5kg; the only exception to this is when a new record is being set. The heaviest "good lift" (within the weight class) is used for final placing in the competition.
