The Claim
Higher resistance training frequency is associated with greater muscle hypertrophy effect sizes compared to lower frequency protocols in healthy adults, with effect sizes of 0.49 ± 0.08 versus 0.30 ± 0.07 (P = 0.002), indicating that more frequent training sessions correlate with enhanced muscular growth 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.
Doing resistance training more often seems to help build more muscle compared to training less often. Research indicates that people who lift weights more frequently experience significantly better muscle growth results than those who train less often.
See the scientific wording
Higher resistance training frequency is associated with greater muscle hypertrophy effect sizes compared to lower frequency protocols, with effect sizes of 0.49 ± 0.08 for higher frequency versus 0.30 ± 0.07 for lower frequency (P = 0.002), indicating that more frequent training sessions correlate with enhanced muscular growth adaptations in healthy adults without chronic disease or injury.
What the research says
1 studyTraining muscles more often, like twice a week instead of once, leads to bigger muscle growth. The study confirms this by showing that higher training frequency results in significantly better muscle-building results.
