Pre-training bone characteristics (bone mineral content, bone area, shoulder/hip width) do not significantly predict the magnitude of appendicular lean tissue mass gains following 10–12 weeks of resistance training in untrained adults.
Do not worry about your bone structure or frame size when starting resistance training. Whether you have wide shoulders or narrow hips, your potential for muscle growth is not determined by your skeleton. Focus on consistent training with progressive overload (increasing weight/reps over time) and adequate protein intake, as these are the drivers of hypertrophy, not your baseline bone density or width.
These provide limited evidence suggesting pre-training bone characteristics do not influence lean tissue mass adaptations to shorter-term resistance training.
Why this rating
Large cohort (n=119), diverse age/sex range, rigorous Bayesian statistical modeling controlling for sex and baseline mass.
Source
Resistance training-induced appendicular lean tissue mass changes are largely unrelated to pre-training bone characteristics in a larger cohort of untrained adults

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
