The Claim
Increases in muscle size resulting from resistance training are not strongly correlated with increases in muscle strength, indicating that muscle hypertrophy and strength gains represent largely independent physiological adaptations.
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.
When people build larger muscles through weight training, the amount of muscle growth does not reliably predict how much stronger they become; muscle size and strength improve through separate biological processes.
See the scientific wording
Resistance training-induced increases in muscle size are not strongly correlated with increases in muscle strength, indicating that hypertrophy and strength gains are largely independent adaptations.
When muscles are trained, they grow bigger by adding more contractile proteins, but getting stronger depends on how well the nervous system activates those muscles. The brain and spinal cord learn to send stronger and more coordinated signals to muscle fibers, recruiting more of them at once and firing them faster, which increases force without needing more muscle size.
What the research says
1 studyEven if two people gain the same amount of muscle from lifting weights, one might get much stronger than the other—this study shows strength isn't just about how big your muscles get; your body's natural biology plays a big role too.
