How many minutes of weekly exercise does Harvard recommend for longevity?

✓ Accepted answer

Harvard T.H. Chan School of Public Health experts recommend at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous activity per week to maximize longevity outcomes.

• Clarify Intensity: Moderate activity includes brisk walking or gardening, while vigorous activity involves jogging, swimming, or cycling. The 75-minute vigorous goal is half the time of the moderate goal but yields similar cardiovascular benefits for healthy adults.
• Consistency Beats Intensity: As of 2025 research updates, even falling short of these targets provides significant health advantages. Consistent movement is more critical for longevity than sporadic, high-intensity bursts, making a steady 30-minute walk daily a sustainable target.
• Supplement, Don't Replace: These exercise guidelines complement, rather than replace, a diet focused on unprocessed, whole foods. Experts emphasize that no expensive supplement or sleep-hacking device can substitute for the physiological benefits of regular movement on metabolic health.
• Practical Application: In the UK, you can use the NHS app to track your weekly active minutes. In the US, many Medicare plans in 2026 now incentivize these specific exercise benchmarks through wearable device integrations, making it easy to monitor your progress toward the 150-minute mark.
