The Claim
High-intensity and low-intensity resistance training produce similar muscle hypertrophy results across various populations when training volume is equated, indicating that training intensity may not be the primary determinant of muscle growth.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Lifting heavy weights and lifting lighter weights can both build muscle just as well for different people, as long as you do the same total amount of work. It suggests that how hard you push might not be the main thing that matters for muscle growth.

High-intensity and low-intensity resistance training produce similar muscle hypertrophy results across various populations, suggesting that training intensity may not be the primary determinant of muscle growth when volume is equated.
What the research says
1 studyThe study looked at lifting heavy weights versus lighter weights and found both can build muscle similarly if you do enough total work, which backs up the claim that how hard you train isn't the main thing for muscle growth.
