How many attempt changes are permitted for lifters in a bench-only competition?

In a bench-only competition, lifters are permitted to make two attempt changes. This rule is designed to provide lifters with the opportunity to adjust their attempts based on their performance or strategic considerations during the competition. It allows participants to optimize their chances for successful lifts while still adhering to the competition structure.

This flexibility is essential in powerlifting, as it accommodates variations in strength, technique, and the lifter's condition on the day of the competition. Lifters often reassess their planned attempts based on prior lifts or the performance of their competitors, so permitting two changes enhances the competitive experience and maintains fairness.

The other options suggest fewer or no changes, which would limit the ability of lifters to adapt and respond to the competition's dynamics, making it less flexible and potentially less exciting for both competitors and spectators.
