“Training volume (sets × reps × load) is the primary driver of muscle hypertrophy, regardless of whether the load is light or heavy.”
Claim checked — strong evidenceMedium riskexercise
Evidence Summary
Multiple well-designed studies consistently support this claim.
Current literature supports total weekly volume as a key predictor of hypertrophy, provided sets are performed near muscular failure.
