Mixed

Manipulations of resistance training variables (such as volume, intensity, or frequency) have a negligible impact on muscle fiber hypertrophy compared to intrinsic biological factors.

Stop obsessing over perfecting your set and rep schemes. Your genetic and biological response to training is the main driver of muscle growth, not whether you do 8 reps or 12. Focus on consistent, hard training and recovery rather than constantly changing variables.

Why this rating

Based on the title alone, which suggests a review or theoretical position paper rather than a single clinical trial; full text needed for specific study designs.
