How much total work you do matters more for muscle growth than how heavy the weights are, as long as you do enough total lifting.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Comprehensive evidence for volume as primary hypertrophy driver
Meta-analysis of volume-equated studies comparing HLRT vs LLRT hypertrophy outcomes across multiple muscle groups and populations
Direct experimental comparison of volume vs load effects
RCT with 100+ adults randomized to different volume-load combinations, precisely matching total work across conditions while varying load intensity
Real-world relationship between volume metrics and hypertrophy
Prospective cohort tracking 200+ resistance trainers' volume-load characteristics and muscle growth over 12+ months with regular DXA scans
