Running vs. Carrying in Human Evolution

This episode is brought to you by BiOptimizers, LMNT, Maui Nui, and Branch Basics. 

When we think about fitness and health, walking is often seen as “too easy” to matter. But this episode challenges that assumption, revealing how walking with weight taps into a deeply human ability that builds strength, resilience, and long-term health in ways most modern workouts miss.

Today on The Dhru Purohit Show, Dhru sits down with Michael Easter to explore walking with weight, a forgotten human practice that quietly shaped our bodies, minds, and resilience, and what happens when modern life removes it. Michael traces the evolutionary roots of carrying and movement, explains why many popular fitness approaches fall short, and reveals how this deceptively simple practice can transform strength, endurance, metabolic health, and mental clarity. Michael challenges our obsession with comfort, unpacks the science behind walking with weight, and shares practical insights on how small, intentional discomfort can help us live stronger, more capable, and more resilient lives in a hyper-convenient world.

He shares these insights through his bestselling books The Comfort Crisis and Scarcity Brain, as well as his newsletter Two Percent.
