Harvard Professor: 7 Big LIES About Exercise, Sleep, Running & Cancer ft. Dr. Daniel Lieberman

7 evolutionary biology-backed corrections to the fitness and health advice you've been sold, from the Harvard professor who literally wrote the book on how the human body evolved.

With Daniel Lieberman

"The entire exercise industry is built on ideas that would have made your grandmother laugh. We didn't evolve to lift heavy things in a gym. We evolved to move all day, occasionally sprint, and rest deeply. Almost everything you think about exercise is wrong."

Daniel Lieberman, on the episode

Dr. Daniel Lieberman is a professor of evolutionary biology at Harvard University and the author of Exercised: a landmark book arguing that most modern fitness advice contradicts the biology humans actually evolved with. In this Diary of a CEO conversation, he walks through the most commonly repeated exercise and health myths and explains why they persist despite evidence against them. Lieberman doesn't reject exercise. He's a marathon runner himself. But he rebuilds the framework from the ground up, starting with what humans actually did for 99% of our evolutionary history and what our biology still expects. The result is a set of recommendations that are often simpler, less intense, and more sustainable than what the fitness industry sells, and considerably more effective.
