"Brilliant...This makes for captivating reading."
-Booklist [starred review]
"Endlessly fascinating and full of surprises. Daniel Lieberman strikes a perfect balance of scholarship, wit, and enthusiasm for his subject. This is easily one of my favorite books of the year."
-Bill Bryson, New York Times best-selling author of A Walk in the Woods and The Body
"Were we born to run, to walk, or to sit on a couch? One of our leading human biologists takes us through millions of years of evolution and diverse cultures around the planet to give us surprising, yet simple, answers. Part user manual for the human body and part detective story exploring our evolution, Exercised will change the way you think about exercise, diet, and your own well-being."
-Neil Shubin, Robert R. Bensley Distinguished Service Professor of Organismal Biology and Anatomy, University of Chicago, and best-selling author of Your Inner Fish
"Excellent. Well-written, amusing, and touching on all our lives. Seldom if ever have I so enjoyed reading a book on any subject, and this one is for all of us-those of us who like to exercise and those of us who don't."
-Richard Leakey, co-author of Origins Reconsidered: In Search of What Makes Us Human
"Fantastic. Such a surprising, erudite, and revelatory look at the natural history of physical activity and why exercise is both so necessary for us and so unnatural. It expands and alters our understanding of exercise, health, motivation, and why we feel the way that we do about treadmills. A must-read for anyone with a working body and mind."
-Gretchen Reynolds, New York Times best-selling author of The First 20 Minutes
"In his earlier work, Lieberman explained how we were 'born to run.' In Exercised, he explains that we were also born to sit, which often leads to obesity, diabetes, high blood pressure, and heart attacks-chronic diseases unknown to early humans. Fortunately, Exercised also explains how physical activity can set us free from these ills. It's both a fascinating read and one that could nudge you toward a healthier (and longer) life."
