The Claim
Resistance training performed at varying distances from muscular failure produces no meaningful differences in muscle hypertrophy, as measured by changes in vastus lateralis and pectoralis major thickness, in trained men.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In trained men, lifting weights close to failure or stopping short of failure results in the same amount of muscle growth, as measured by changes in muscle thickness.
See the scientific wording
Resistance training proximity to failure does not produce meaningful differences in muscle hypertrophy in trained men, as changes in vastus lateralis and pectoralis major thickness were within the measurement error threshold across all training groups, indicating that training to failure is not necessary for muscle growth in this population.
When muscles are worked with enough weight, they trigger the same maximum level of protein building no matter how close to exhaustion the set goes. Once that maximum is reached, doing more reps or pushing harder doesn't build more muscle.
What the research says
1 studyFor guys who already lift regularly, pushing every set to absolute exhaustion doesn’t help you grow bigger muscles any more than stopping a few reps short. The study found no clear difference in muscle growth between the two approaches.
