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.

Description
1 study reviewed
In plain English

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.

Why this might work

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.

    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.
