Summary

People who lifted weights until they couldn't do another rep got the same leg muscle growth as those who stopped just before failure — but the ones who pushed to failure felt way more tired after each set.

Surprising Findings

Training to failure didn’t lead to more muscle growth — even though it caused significantly more fatigue.

Common fitness lore says pushing to failure maximizes muscle growth; this study shows it’s not necessary — and may even be counterproductive due to excessive fatigue.

Practical Takeaways

For leg workouts, stop 1–2 reps short of failure on leg press and leg extensions to reduce fatigue while maintaining muscle growth.
