Scientific research strongly supports this positive correlation. A meta-analysis of 16 observational studies published in *PLOS One* (Wang et al., 2023) shows that low muscle mass is associated with a 57% higher risk of premature death. Another large observational meta-analysis (2023) confirms that loss of muscle tissue directly harms life expectancy. However, the image of the ultra-muscular body should be qualified: science primarily validates the importance of avoiding age-related muscle wasting rather than infinite benefits for extremely voluminous physiques. Furthermore, large cohort observational studies (such as the UK Biobank) remind us that physical strength and muscle quality are even more robust indicators of longevity than mere volume. The claim is therefore very solid, but the wellness advantage lies above all in regular training to maintain functional strength over the years.

What the graded evidence says

Evidence: B

Linked to, not proven to cause.

Effect: all-cause mortality by muscle strength (grip) and by muscle mass vs strength — grip strength: HR 1.16 (95% CI 1.12-1.20) per 5-kg lower grip, 42 cohorts, ~3M people; low muscle strength independently ~2x mortality odds regardless of muscle mass
Measured on: community-dwelling and older adults

This is an association from observational studies, not proof that adding muscle causes longer life. Strength is a stronger predictor of survival than muscle mass by itself.
