The Claim
In resistance-trained men, muscle hypertrophy in the elbow extensors shows no statistically significant difference across low, moderate, and high training volumes, with a non-significant trend toward greater hypertrophy at higher volumes.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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.
In men who regularly lift weights, increasing the number of sets for elbow extensor exercises does not result in significantly more muscle growth, even though higher volumes show a slight, non-significant tendency to produce more growth.
See the scientific wording
In resistance-trained men, muscle hypertrophy in the elbow extensors does not differ significantly between low, moderate, and high training volumes, despite a trend toward greater growth with higher volume, suggesting a possible muscle-specific threshold or adaptation limit.
When muscles are trained, mechanical stress triggers signals that tell muscle cells to build more protein. In some muscles, this signal keeps getting stronger with more training, so they grow bigger. But in the elbow extensors, the signal reaches a maximum level after a certain amount of training, and adding more sets doesn't make it any stronger, so the muscle stops growing beyond that point.

1 studyStudy: Resistance Training Volume Enhances Muscle Hypertrophy but Not Strength in Trained Men
For trained guys, doing more sets doesn’t make your triceps grow much more, even though it helps your biceps and thighs grow bigger — so your triceps might have a limit on how much they can grow from extra sets.
