If you're just casually working out, doing a few sets of bicep curls with one arm is just as good for getting stronger as doing a lot more sets—your muscles don't need extra work to keep improving past a certain point.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Evidence from Studies

Increasing set volume relative to baseline does not augment skeletal muscle adaptations when compared to maintenance of baseline training volume in recreationally trained individuals

Randomized Controlled Trial
Human
2025 Apr

The study found that doing the usual number of arm curls gave the same strength gains as doing more curls — so doing extra sets doesn’t help beyond a certain point.

Similar Assertions

If you're an average gym-goer doing one-arm bicep curls, doing more sets than your usual routine won't make your arm muscles bigger or stronger—your gains plateau at your current volume.

If you're someone who works out a little but not super hard, just keeping up your usual routine for 3 months can actually make your biceps bigger and stronger — you don’t need to go all out.

Both methods probably push your muscles to about the same level of fatigue, which is why they end up making your arms grow about the same amount.

If you do the same amount of work with your arm in front or behind you, you'll get just as strong at lifting heavy weights — the position doesn't matter.

If you're lifting weights and stretch your biceps and triceps really far—like at the bottom of a curl or overhead extension—you'll build muscle just as well as if you move all the way up and down, as long as you get that deep stretch.
