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.

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 even if people just keep doing their usual workout routine without adding more sets, their arm muscles still get bigger and stronger over 12 weeks — so you don’t need to train harder to see results.

Similar Assertions

If regular gym-goers train their biceps by lifting in a way that stretches the muscle more, they’ll likely gain more muscle size over two months.

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 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 untrained adult men lift weights twice a week for 8 weeks, doing 4-6 sets of 8-12 reps until they can't do any more, their upper arm muscles will get bigger - this is measurable with ultrasound or other imaging.

Doing arm exercises that shorten and lengthen the muscles might help build arm size a little, but the evidence isn't super strong—there's only about a 55% chance it's better than just lengthening exercises.
