The Minimum Effective Dose: Minutes to Major Health Gains

The Longevity Podcast: Optimizing HealthSpan & MindSpan

Send us a text

We show how the minimum effective dose of exercise delivers outsized gains for heart and brain health with minutes, not hours. The science points to a steep benefit curve from zero to brief, intense movement, with clear targets you can hit today.
• redefining exercise as a threshold, not a time block
• nonlinear dose–response curve and why the first minutes matter most
• five to ten minutes of slow jogging and 30% lower mortality
• pace beating volume for health outcomes
• brisk 15-minute walks versus long slow walks
• brain health benefits via blood flow and BDNF
• step targets plateauing at 5,000–7,500 for cognition
• accessibility for older or frail adults with modified MED
• practical ways to integrate short, intense breaks into the day
• public health implications of mandated micro-bursts
We challenge you to think what's one specific small adjustment you could make today to hit that minimum effective dose and gain the biggest health return of your life?
