The Claim
In untrained adults, baseline appendicular lean tissue mass is weakly correlated with resistance training-induced gains in lean mass (r = 0.15–0.16), but this association becomes non-significant after adjusting for sex, indicating that initial muscle size is not a strong predictor of hypertrophy response.
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.
If you're new to lifting weights, having more muscle at the start doesn't really mean you'll gain more muscle from training — it's not a strong predictor of results, especially once you account for whether someone is male or female.
See the scientific wording
Baseline appendicular lean tissue mass is weakly associated with resistance training-induced gains in lean mass (r = 0.15–0.16) in untrained adults, but this relationship diminishes after adjusting for sex, suggesting that initial muscle size is not a strong predictor of hypertrophy response.
What the research says
1 studyThe study found that how much muscle you start with doesn’t strongly predict how much muscle you’ll gain from lifting weights, especially when you account for differences between men and women.
