In industrialized nations, our sedentary lifestyles have contributed to skyrocketing rates of obesity and diseases like diabetes. A key remedy, we are told, is exercise - voluntary physical activity for the sake of health. However, most of us struggle to stay fit, and our attitudes to exercise are plagued by misconceptions, finger-pointing and anxiety.But, as Daniel Lieberman shows in Exercised, the first book of its kind by a leading scientific expert, we never evolved to exercise. We are hardwired for moderate exertion throughout each day, not triathlons or treadmills. Drawing on over a decade of high-level scientific research and eye-opening insights from evolutionary biology and anthropology, Lieberman explains precisely how exercise can promote health; debunks persistent myths about sitting, speed, strength and endurance; and points the way towards more enjoyable and physically active living in the modern world.
