When people lift weights without pushing to their absolute limit, they actually get stronger faster than if they push to failure, as long as the total amount of lifting isn't the same. This comes from a big review of studies on adults.

Lifting weights until you can't do any more reps doesn't make you stronger than stopping a few reps short, according to a big review of studies.

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.

Lifting weights until you can't do any more reps makes your muscles grow bigger than lifting weights without pushing to your limit, based on a big review of studies.

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.
