Summary

One leg trained to failure, the other stopped just before failure. After 10 weeks, both legs grew and got stronger just the same.

Surprising Findings

Training just short of failure produced slightly *higher* muscle growth (18.1% vs 13.5%) despite lower volume.

Most lifters assume more pain and effort = more growth, but here, less effort led to numerically greater hypertrophy.

Practical Takeaways

Stop 1–2 reps before failure on your sets to reduce fatigue and save energy while maintaining muscle and strength gains.
