Summary

If exercise is healthy, why do so many people avoid doing it? If we're born to be active, why is it so hard to keep your New Year's resolutions about exercise? On this episode, learn about the powerful instincts that cause us to avoid exercise even though we know it's good for us.

Dan Lieberman, author of the new book Exercised: Why Something We Never Evolved to Do Is Healthy and Rewarding, tells the story of how we never evolved to do voluntary physical activity for the sake of health, and helps us think about exercise in a whole new way. 

About our guest

Daniel Lieberman is a professor of human evolutionary biology at Harvard University, a member of The Leakey Foundation's Scientific Executive Committee, and a pioneering researcher on the evolution of human physical activity. His research is on how and why the human body looks and functions the way it does. He has long been fascinated by the evolution of the human head but his main focus is currently on the evolution of human physical activity. He is especially interested in how evolutionary approaches to activities such as walking and running, as well as changes to our body's environments (such as wearing shoes and being physically inactive) can help better prevent and treat musculoskeletal diseases. To address these problems, he integrates experimental biomechanics and physiology in both the laboratory and the field with analyses of the human fossil record.

And along with the reported three quarters of all adults in America,

I'm planning to make some changes in 2021. I'm making one of the most popular and basic New Year's

resolutions to improve my health and get more exercise. I'll admit this is not the first year I've

promised myself to walk 10,000 steps a day or do yoga or lift weights three times a week.

I make myself the same promise pretty much every year.

And every year I feel bad about myself when it doesn't happen.

But not this time.

No more feeling bad.

Because what if I told you that the reason it can be so
