Exercise Science is Killing Your Gains

Summary by Krater

An evidence-based deep dive into muscle growth volume recommendations, critiquing the scientific literature and arguing that the data are too flawed and noisy to dictate precise optimal set ranges.

Answers: Are exercise science volume recommendations for muscle growth accurate and useful?

• resistance training volume
• muscle hypertrophy
• exercise science methodology
• scientific study limitations
• reproducibility crisis
• statistical power
• perceived exertion in lifting
• volume cycling

What it concludes

• Most exercise science volume literature suffers from severe limitations including small sample sizes, lack of control over confounding variables, and faulty statistical analyses.
• Small sample sizes in lifting studies result in very low statistical power, meaning most studies are set up to fail at detecting important differences.
• Studies commonly rely on untrained participants or use training protocols that do not reflect how advanced lifters actually train.
• Subjective rating systems like RPE and RIR are unreliable because lifters' self-selected loads frequently miss target repetition ranges.
• Individual responses to training volume vary wildly, rendering population-level optimal volume ranges unreliable for individuals.
• Volume cycling and progressive overload matter more for long-term muscle growth than strictly adhering to generalized volume recommendations.
