Format: All citations follow APA 7th edition style. Author surnames are listed first, followed by initials. Journal titles are italicised. DOIs are presented as hyperlinks where available.
Verification recommended: All citations should be verified via Consensus (consensus.app), PubMed (pubmed.ncbi.nlm.nih.gov), or Google Scholar before use. DOIs can be resolved at doi.org.
Consensus review: The Consensus AI review for this post confirmed the core evidence base. All primary claims are well-supported across the cited sources. The Consensus review specifically confirmed: (1) the 10–20% mortality risk reduction associated with regular muscle-strengthening activity; (2) the J-shaped dose–response relationship with maximal benefit at approximately 30–60 minutes per week; (3) meaningful improvements in bone mineral density from both gym-based and band/bodyweight protocols; and (4) the effectiveness of resistance training for improving insulin sensitivity, functional capacity, and balance in older and frail populations.
