What is required of lifters regarding their declared weight class during weigh-ins?

Lifters must weigh in under their declared weight class or exactly at it to ensure fair competition within the designated weight categories. This rule is critical because powerlifting is structured around specific weight classes to promote equality among participants. When lifters declare a weight class, they are committing to compete against others who are within the same weight range, thus ensuring that strength and skill, rather than body mass, are the primary determinants of performance.

By requiring lifters to meet this specification, the International Powerlifting Federation maintains the integrity of the competition and prevents any advantages that could arise from weighing more than the declared limit. This regulation emphasizes the importance of preparation in terms of both training and body composition, underscoring the strategic elements of weight management in the sport.
