No matter if you use a pyramid, go to failure, or stick to a normal routine, your muscle fibers don’t change their angle or how they’re packed together any more with one method than another—when you do the same total work.
Scientific Claim
In well-trained men, 12 weeks of crescent pyramid, drop-set, or traditional resistance training with equalized volume results in comparable increases in pennation angle of the vastus lateralis (approximately 10.3–11.0%), suggesting that muscle fiber reorganization is not enhanced by specialized training protocols.
Original Statement
“All protocols increased PA (TRAD = 10.6%; CP = 11.0%; DS = 10.3%) similarly.”

Appropriate Language Strength
definitive
Can make definitive causal claims
Assessment Explanation
Ultrasound measurements are objective and the within-subject design minimizes noise. The lack of statistical differences supports definitive language.
Evidence from Studies
Supporting (1)
When well-trained men did three different types of weight workouts with the same total effort, all of them made their thigh muscles look about the same in terms of fiber angle—so no special method was better than the regular one.
