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.

recreationally trained individuals performing unilateral elbow flexion training

Action

increasing set volume beyond baseline does not lead to greater increases in

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 gave some people more sets of bicep curls than others, but both groups ended up with the same muscle growth and strength gains — so doing more sets didn’t help beyond the usual amount.

Similar Assertions

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.

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.

If you're someone who lifts weights for fun and not professionally, your upper arm muscles grow about the same amount near the shoulder, middle, and elbow—no matter if you do more or the same number of sets and reps.

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 use the same weight and do the same number of reps, it doesn't matter if you curl with your arm in front or behind you — what matters is just doing it consistently and getting stronger over time.
