If you push your muscles until they can't do another rep, you create more force per set—which can help if you're not doing many sets, but might hurt your progress if you're already doing a lot of work.

Effects of resistance training performed to repetition failure or non-failure on muscular strength and hypertrophy: A systematic review and meta-analysis

Systematic Review With Meta-Analysis
Human
2022 Mar

This study found that lifting until you can't do another rep doesn't help you get stronger or bigger more than stopping before failure — and if you're already doing a lot of reps, going to failure might even hurt your progress.

Acute effects of equated volume-load resistance training leading to muscular failure versus non-failure on neuromuscular performance

Randomized Controlled Trial
Human
2020 May

When people lift weights until they can't do another rep, their muscles get way more tired—even if they do the same total amount of work as someone who stops earlier. This means going to failure makes each set harder on your body, which helps if you're doing few sets, but hurts if you're already doing a lot.

Low-Load Resistance Training to Volitional Failure Induces Muscle Hypertrophy Similar to Volume-Matched, Velocity Fatigue

Randomized Controlled Trial
Human
2022 Jun 1

This study found that lifting light weights until you can't do another rep builds muscle just as well as doing more reps without going all the way to failure — meaning going to failure can make up for doing fewer total reps. It supports the idea that failure helps when you're not doing much volume.

Similar muscle hypertrophy following eight weeks of resistance training to momentary muscular failure or with repetitions-in-reserve in resistance-trained individuals

Randomized Controlled Trial
Human
2024 Jan

The study found that lifting until you can't do another rep doesn't make your muscles grow more than stopping just before failure — as long as you do the same total amount of work. So, pushing to failure isn't needed, and might even make you more tired for no extra gain.

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.

Similar Assertions

Doing more sets of weightlifting seems to build muscle more reliably than how close you get to failing on each set—whether you stop short or push to exhaustion doesn’t change the muscle growth much if you’re doing the same number of sets.

If you lift weights until you can't do another rep or stop a little earlier—but do the same total amount of work—your muscles will grow and get just as strong either way. So you don’t have to push to absolute failure to see results.

If you don’t push yourself to the absolute limit during weight training, you might actually get stronger faster—because you can do more total lifts overall.

If you lift weights until you can't do another rep, it won't hurt your muscle growth or strength—as long as you're doing the same total amount of work as someone who stops short of failure. So going all the way to failure is totally fine.

If you lift weights without pushing yourself to total exhaustion, you might get stronger faster—especially if you end up doing more total lifts overall compared to people who do go all the way to failure.
