Whether you lift weights using a pyramid, go to failure, or stick to a standard routine, if you do the same total amount of work, your leg strength improves by about the same amount—around 25%—after 12 weeks.

Scientific Claim

In well-trained men, 12 weeks of crescent pyramid, drop-set, or traditional resistance training with equalized volume results in equivalent gains in leg press one-repetition maximum strength, with average increases of approximately 25% across all methods, demonstrating that strength gains are not enhanced by specialized protocols when volume is matched.

Original Statement

All protocols showed significant and similar increases in leg press (TRAD = 25.9%; CP = 25.9%; DS = 24.9%).

Assessment Explanation

The RCT design with randomization and control allows definitive causal claims. The near-identical effect sizes and lack of statistical difference support the use of definitive language.

When trained guys did three different kinds of leg workouts with the same total effort, they all got about 25% stronger—no method was better than the others.
