The Claim
Untrained young men who perform pec deck resistance training three times per week for 12 weeks experience approximately 43–46% increases in maximal strength, as measured by 1-repetition maximum, regardless of whether they perform one set or three sets per session, suggesting that low-volume training is sufficient for strength gains in novice lifters.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you're new to lifting, doing just one set of pec deck exercises three times a week can make you just as strong as doing three sets — after 12 weeks, both groups get about 45% stronger.
