Today, most of us tend to medicalize exercise, turning it into something that we “have” to do. Case in point: the treadmill. If our main goal was enjoyment, there’s no way we’d regularly spend 45 minutes walking in place on these expensive machines.
But our relationship with exercise — or, more generally, physical activity — was not always so discrete and joyless. For much of human history, people got plenty of physical activity by not only walking long distances, but also by doing activities that were both necessary and socially rewarding, like hunting, dancing, and sports.
Harvard biologist Daniel Lieberman argues it’s time to rethink our relationship with exercise, and to understand physical activity as a complex and integral part of human evolution. After all, while walking thousands of steps through the environment to find our next meal was a major part of our evolution, walking on the treadmill was not.
