The Claim

In untrained adults participating in 10–12 weeks of supervised resistance training, pre-existing bone characteristics—including bone mineral content, bone area, shoulder width, and hip width—show weak positive correlations (r = 0.10–0.24) with gains in appendicular lean tissue mass, suggesting that baseline skeletal structure is largely unrelated to short-term muscle hypertrophy responses.

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 plain English

If you're new to strength training, your bone size or density doesn't really predict how much muscle you'll gain in the first few months—people with all kinds of frames tend to gain muscle at similar rates.

See the scientific wording

In untrained adults undergoing 10–12 weeks of supervised resistance training, pre-existing bone characteristics such as bone mineral content, bone area, shoulder width, and hip width show weak positive associations (r = 0.10–0.24) with increases in appendicular lean tissue mass, indicating that skeletal structure is largely unrelated to short-term muscle hypertrophy responses.

  1. Study: Resistance training-induced appendicular lean tissue mass changes are largely unrelated to pre-training bone characteristics in a larger cohort of untrained adults

    The study looked at whether someone’s bone size affects how much muscle they gain during short-term weight training. It found that bone structure doesn’t really predict muscle growth, which supports the claim.
