The t-shirt's sleeve should not be longer than the lifter's ________.

The appropriate answer is that the t-shirt's sleeve should not be longer than the lifter's elbows. In competitive powerlifting, the attire worn by lifters is subject to specific regulations to ensure fairness and uniformity across competitions. The sleeve length is crucial as it can affect the lifter's performance, particularly during the bench press.

If the sleeves are too long, they may interfere with the lifter's ability to achieve proper positioning and leverage, potentially disadvantaging them compared to those with compliant attire. By specifying that the sleeves must not extend beyond the elbows, the rules aim to maintain a standardized approach that enhances competition integrity and athlete safety.

Sleeves longer than the elbows could also lead to confusion about the lift's execution and the lifter's compliance with the equipment guidelines. Thus, keeping the t-shirt's sleeves at or above the elbows is essential for adherence to the established uniform requirements in powerlifting competitions.
