Small Amounts Yield Big Longevity Gains
- Regular physical activity may lower premature death risk by about 30% compared to sedentary people.

Start With Daily Walking
- Aim for at least 20–30 minutes of moderate activity daily to capture most longevity benefits described in guidelines.
- Start with walking if sedentary since it's safer and easier to sustain than running.
Follow Comprehensive Activity Guidelines
- Follow official guidelines: at least 150 minutes per week of moderate aerobic exercise (≈20+ minutes/day).
- Add muscle-strengthening, flexibility, and balance training at least twice weekly for older adults.
