Exercised
If exercise is healthy (so good for you!), why do many people dislike or avoid it? These engaging stories and explanations will revolutionize the way you think about exercising—not to mention sitting, sleeping, sprinting, weight lifting, playing, fighting, walking, jogging, and even dancing. “Strikes a perfect balance of scholarship, wit, and enthusiasm.” —Bill Bryson, New York Times best-selling author of The Body • If we are born to walk and run, why do most of us take it easy whenever possible? • Does running ruin your knees? • Should we do weights, cardio, or high-intensity training? • Is sitting really the new smoking? • Can you lose weight by walking? • And how do we make sense of the conflicting, anxiety-inducing information about rest, physical activity, and exercise with which we are bombarded? In this myth-busting book, Daniel Lieberman, professor of human evolutionary biology at Harvard University and a pioneering researcher on the evolution of human physical activity, tells the story of how we never evolved to exercise—to do voluntary physical activity for the sake of health. Using his own research and experiences throughout the world, Lieberman recounts without jargon how and why humans evolved to walk, run, dig, and do other necessary and rewarding physical activities while avoiding needless exertion. Exercised is entertaining and enlightening but also constructive. As our increasingly sedentary lifestyles have contributed to skyrocketing rates of obesity and diseases such as diabetes, Lieberman audaciously argues that to become more active we need to do more than medicalize and commodify exercise. Drawing on insights from evolutionary biology and anthropology, Lieberman suggests how we can make exercise more enjoyable, rather than shaming and blaming people for avoiding it. He also tackles the question of whether you can exercise too much, even as he explains why exercise can reduce our vulnerability to the diseases mostly likely to make us sick and kill us.
The Truth about Exercise
A natural history of exercise seeking to answer a fundamental question: were you born to run or rest? Follows the evolutionary story of human physical activity and inactivity and considers how anthropological and evolutionary approaches can help us exercise better in the modern world
The Story of the Human Body
Story of the Human Body explores how the way we use our bodies is all wrong. From an evolutionary perspective, if normal is defined as what most people have done for millions of years, then it's normal to walk and run 9 -15 kilometers a day to hunt and gather fresh food which is high in fibre, low in sugar, and barely processed. It's also normal to spend much of your time nursing, napping, making stone tools, and gossiping with a small band of people. Our 21st-century lifestyles, argues Dan Lieberman, are out of synch with our stone-age bodies. Never have we been so healthy and long-lived - but never, too, have we been so prone to a slew of problems that were, until recently, rare or unknown, from asthma, to diabetes, to - scariest of all - overpopulation. Story of the Human Body asks how our bodies got to be the way they are, and considers how that evolutionary history - both ancient and recent - can help us evaluate how we use our bodies. How is the present-day state of the human body related to the past? And what is the human body's future? Daniel Lieberman is the Chair of the Department of Human Evolutionary Biology at Harvard and a leader in the field. He has written nearly 100 articles, many appearing in the journals Nature and Science, and his cover story on barefoot running in Nature was picked up by major media the world over. His research and discoveries have been highlighted in newspapers and magazines, including The New York Times, The Boston Globe, Discover, and National Geographic.
