Final answer:
In powerlifting competitions, competitors complete three lifts which are the deadlift, squat, and bench press, all of which are included in the event.
Step-by-step explanation:
The exercise included in a powerlifting competition is D: All of the above. Powerlifting is a strength sport that consists of three attempts at maximal weight on three lifts: the deadlift, the squat, and the bench press. Competitors are judged based on the maximum amount of weight lifted for each exercise, and the sum of the best lift from each exercise contributes to the competitor's total score.
During the deadlift, the powerlifter lifts a loaded barbell from the ground to a standing position. The squat involves the lifter placing a weighted barbell on their shoulders and then squatting down before standing back up. The bench press requires the athlete to lie on a bench and press a weight upwards from chest level until the arms are fully extended. Each of these exercises requires not only immense strength but proper technique to execute safely and effectively.
