The Claim
Resistance training frequency is associated with increases in strength gains but not consistently with muscle hypertrophy, indicating a stronger relationship with neural adaptations than with muscle growth.
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.
Higher frequency of resistance training is linked to greater strength improvements but not reliably to increases in muscle size, suggesting that strength gains are more closely tied to changes in nervous system function than to muscle enlargement.
See the scientific wording
Resistance training frequency is associated with strength gains but not consistently with muscle hypertrophy, suggesting that frequency may play a more critical role in neural adaptations than in muscle growth.
Training more often trains the brain and nerves to activate more muscle fibers at once, making you stronger without making the muscles bigger.
What the research says
1 studyDoing exercises more often each week helps you get stronger, but doesn’t necessarily make your muscles bigger. That’s because getting stronger might just mean your brain and nerves are getting better at telling your muscles when and how to contract.
