Paleoanthropologist Daniel Lieberman explores how our ancestors engaged in physical activity and examines why modern exercise feels so difficult despite being so good for our health and wellbeing.

From gym class and team sports to running clubs and yoga courses, we have spent our lives being told that we need to move our bodies to stay healthy.

But if physical activity is good for our minds and bodies, why is it so hard to stick with it? Are we just lazy, or are our bodies not built for modern exercise?

Daniel Lieberman is a paleoanthropologist and professor at Harvard University known for his research on the evolution of the human body.

In his 2020 book, Exercised, Lieberman debunks myths about how our hunter-gatherer ancestors moved and explains why most of us aren't built for modern fitness regimes.
