Daniel Lieberman On Why We Avoid Exercise

Renee Bright

The new year means a lot of us are committing to new exercise routines — routines we’re going to “get right” this time. Only, what if we didn’t evolve to exercise at all?

Our guest, paleoanthropologist Daniel Lieberman, says regular exercise — working out, on purpose, to get healthier — was never part of the plan for natural selection. (Hey, as long as the species keeps breeding, right?) But we’re also not supposed to sit around all day and do nothing. We did evolve to use our bodies and even to work them pretty hard — when necessary. With medical professionals lamenting our sedentary lifestyles, the key, Daniel Lieberman told us, is to exercise the right way. He'll join us Friday at noon to share his research.
