How little exercise does it really take to extend your life? This episode breaks down the science behind the minimum effective dose and reveals why small, strategic bursts of movement can create massive benefits for longevity, heart health, and brain resilience. The research shows a striking nonlinear dose–response curve, meaning the first few minutes of activity deliver the biggest return—and far more than most people realize.

We explore how just five to ten minutes of jogging is linked to large reductions in mortality, why brisk 15-minute walks outperform slow multi-hour strolls, and how intensity—not volume—drives adaptation by crossing the physiological challenge threshold. You’ll learn how even brief sessions increase blood flow and elevate BDNF, supporting sharper cognition and long-term brain protection. We also discuss accessibility for older or frail adults and what the data reveals about Alzheimer’s risk plateauing around 5,000–7,500 steps per day.

The episode ends with practical strategies for integrating short, high-impact movement bursts into your daily routine—no gym, no hour-long sessions, no barriers.
