‘Being lazy is normal’ – Professor

Imagine you’ve set your alarm to go for an early-morning run before work. But when it goes off at 6, the embrace of your warm, cozy bed is too enticing and you never make it out the door. Or perhaps you’ve packed exercise clothes with plans to hit a spin class after work. But then the allure of happy hour, or even your couch, persuades you to skip it. Even those with the best of intentions often struggle to motivate themselves to work out. There’s almost always a powerful temptation to do something, or anything, else.

This can feel like a personal failing, as though the decision not to exercise were a sign of weak character, or at least willpower. But you may just be giving in to humans’ evolutionary instinct to be lazy. At least that’s the theory of one Harvard professor who believes our ancestors exerted so much energy hunting and gathering that they sought rest whenever they could. We are predisposed to want to conserve energy.

Daniel Lieberman, an expert in human evolutionary biology, posed in a 2015 paper, “Is Exercise Really Medicine? An Evolutionary Perspective,” that it’s not our natural inclination to exercise for health alone. “It is natural and normal to be physically lazy,” he writes. “I predict that hunter-gatherers in the Kalahari or the Amazon are just as likely as 21st century Americans to instinctually avoid unnecessary exertion. Although a small percentage of people today exercise as a form of medicine, doing their prescribed dose, the vast majority of people today behave just as their ancestors by exercising only when it is fun (as a form of play) or when necessary.” Read more
