Exercise is the closest thing we have to a miracle drug. Regular physical activity reduces the risk of nearly every chronic disease, improves mental health, and is one of the strongest predictors of how well you'll age.
Key Insights
Just 11 Minutes a Day
strong evidenceA 2023 meta-analysis in the British Journal of Sports Medicine found that just 11 minutes of brisk walking per day is associated with a 25% lower risk of premature death. You don't need a gym membership.
Zone 2 Cardio
moderate evidenceTraining at a conversational pace (Zone 2) for 150+ minutes per week improves mitochondrial function — the energy factories of your cells. This is the foundation recommended by longevity-focused physicians like Peter Attia.
Strength Training & Aging
strong evidenceMuscle mass naturally declines after 30. Resistance training 2–3 times per week can slow or reverse this, reducing fall risk, improving bone density, and supporting metabolic health well into old age.
Sitting Is the New Smoking
strong evidenceProlonged sitting is independently associated with higher mortality — even in people who exercise. Breaking up long sitting bouts with 5-minute movement breaks every 30–60 minutes makes a measurable difference.
