Doing eight sets of heavy weightlifting per workout builds strength faster and better than just doing one set, especially for people who already lift weights regularly. This finding is from the abstract summary - full study details were not available.
Claim Context
Performing eight sets of high-intensity resistance exercise per session produces faster and greater strength gains compared to performing only one set in trained males, with significant differences emerging as early as three weeks into a training program. This volume-dependent adaptation suggests that higher training volumes may optimize strength development in resistance-trained individuals over a 10-week period, highlighting the practical implications for programming.
“The 8-set group was significantly stronger than the 1-set group after 3-weeks of training (7.9% difference, P < 0.05), and remained stronger after 6 and 10-weeks of training (P < 0.05).”

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.
A systematic review would synthesize all available RCTs comparing different set volumes, providing a comprehensive estimate of the average effect size and consistency of strength gains across diverse populations.
A Cochrane-style systematic review and meta-analysis of at least 10 randomized controlled trials comparing 1-set vs 8-set resistance training protocols in trained males, measuring 1-RM strength changes over 8-12 weeks.
A well-designed RCT could definitively establish whether increasing set volume from 1 to 8 causes greater strength gains by controlling for confounding variables and minimizing bias.
A double-blind, parallel-group RCT with 120 trained males randomized to 1-set or 8-set protocols, matched for baseline strength, training frequency, and nutrition, with 1-RM squat measured by blinded assessors at 3, 6, and 10 weeks.
A prospective cohort study could track naturally occurring variations in training volume among athletes to observe real-world associations between set volume and strength progression over time.
A 12-month prospective cohort study tracking 200 resistance-trained males, recording their self-reported weekly set volumes and measuring quarterly 1-RM strength changes while controlling for age, training history, and diet.
