Is it true that training to muscular failure produces more muscle growth than stopping a few repetitions short of failure?
No. Multiple meta-analyses and controlled trials report no significant difference in muscle hypertrophy between training to muscular failure and stopping short of failure, with some evidence favoring non-failure for strength. The evidence does not support the claim that failure training produces more muscle growth.
