The Claim
In young, mostly male adults, higher weekly resistance training frequency is associated with greater strength gains but not with muscle hypertrophy.
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 young adult men, doing resistance training more often each week leads to larger increases in strength but does not lead to larger muscle size.
See the scientific wording
In young, mostly male adults, higher weekly resistance training frequency is associated with greater strength gains but not with muscle hypertrophy, suggesting frequency may play a more specific role in neural adaptations than in muscle growth.
Training more often trains the brain and spinal cord to send stronger and more frequent signals to the muscles, making them contract harder without changing muscle size.
What the research says
1 studyFor young men, doing resistance training more days a week helps you get stronger faster, but doesn’t make your muscles much bigger — it’s like your brain and nerves get better at telling your muscles when and how to lift, not your muscles growing larger.
