The Claim
In young untrained men, increasing resistance training volume from 1 to 3 sets per exercise does not lead to greater strength gains in upper-body muscles, as both training volumes result in similar improvements in upper-body one-repetition maximum (1RM) performance over an 11-week period.
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.
For young guys just starting out at the gym, doing 1 set or 3 sets of each exercise gives about the same strength boost in the upper body after 11 weeks.

In young untrained men, increasing resistance training volume from 1 to 3 sets per exercise does not result in greater strength gains in upper-body muscles, as both regimens produced similar improvements in upper-body 1RM performance over 11 weeks.
When someone starts lifting weights, their nervous system quickly learns how to use their muscles more efficiently. After just one set of exercises, the brain and nerves have already improved enough to activate nearly all the muscle fibers needed for maximum strength. Doing more sets doesn't make the nervous system any better at this, so strength doesn't increase further.
What the research says
1 studyFor guys just starting the gym, doing one set or three sets of upper-body exercises like bench press leads to about the same strength gain after 11 weeks — the study found no extra benefit from doing more sets.
