Exercised by Daniel E. Lieberman Summary
Overview of Exercised
In "Exercised," Harvard evolutionary biologist Daniel Lieberman reveals why humans naturally avoid unnecessary exertion yet paradoxically need movement. Endorsed by Runner's World's Amby Burfoot, this myth-busting exploration explains why our ancestors never "worked out" - and how modern exercise culture gets evolution all wrong.

The Exercise Paradox: Why We Avoid What We Need
Picture this: Ernesto, a 70-year-old Tarahumara man from Mexico's Sierra mountains, looks puzzled when asked about "training" for running competitions. "Why would anyone run when they don't have to?" he asks. As a subsistence farmer who grows all his food without machines, Ernesto remains remarkably fit without ever "exercising." His perspective highlights the central paradox explored in "Exercised": humans evolved to be physically active but also to avoid unnecessary exertion. Our ancestors walked miles daily, carried heavy loads, and occasionally sprinted from predators - not to stay fit, but because survival demanded it. Meanwhile, they rested whenever possible to conserve precious calories. This evolutionary legacy explains why exercise feels like a chore. When you take the escalator instead of stairs or circle a parking lot looking for a closer spot, you're not being lazy - you're following ancient programming to conserve energy. Remember those documentaries portraying indigenous people as natural superathletes untainted by civilization? That's largely fiction. What surprised researchers most upon first visiting Hadza hunter-gatherer camps in Tanzania was finding everyone sitting around, apparently doing nothing. While Hadza do leave camp daily to hunt and gather, with women walking miles to dig for tubers and men tracking animals for 7-10 miles, much of their time in camp is spent resting and socializing. The problem isn't our natural inclination to rest - it's that modern environments have made physical activity optional while making calorie-dense food abundant. This "mismatch" between our evolved tendencies and current environment explains why half of American adults fail to meet basic activity guidelines, contributing to epidemic levels of chronic disease.
