Meeting both aerobic (≥150 min/week) and muscle-strengthening (≥2 sessions/week) physical activity guidelines is associated with the lowest prevalence of chronic health conditions compared to meeting neither, only aerobic, or only muscle-strengthening guidelines.
To maximize protection against chronic diseases like heart disease, diabetes, and depression, aim for at least 150 minutes of moderate aerobic activity (like brisk walking) per week PLUS two days of muscle-strengthening activities (like resistance bands or bodyweight exercises). Doing both together offers significantly better health outcomes than doing just one.
After adjustment for covariates... meeting the combined MVPA-MSA guidelines was associated with the lowest PRs for all health conditions (APR range: 0.44–0.76), and the clustering of ≥6 chronic health conditions (APR = 0.33; 95% CI: 0.31–0.35).
Why this rating
Large sample size (n=383,928) and robust statistical adjustment, but cross-sectional design prevents causal inference.

- 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
