The myth-busting science behind our modern attitudes to exercise: what our bodies really need, why it matters, and its effects on health and wellbeing.

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.
