Ejercicio: por qué algo para lo que nunca evolucionamos es saludable y gratificante

Book Description

Why is something as beneficial as exercise so difficult to maintain? In Exercised, renowned evolutionary biologist Daniel E. Lieberman addresses this paradox from a unique perspective: human evolution. The book debunks myths about exercise and explains why our bodies are not designed to run marathons or lift weights, but rather to move efficiently in environments of scarcity. Through an engaging and rigorous narrative, Lieberman proposes that understanding our evolutionary roots is key to adopting a healthier relationship with physical activity.

This work combines science, history, and anecdotes to offer a comprehensive view of why we move—and why we often prefer not to. Without dogmatism, the author invites us to reflect on how to integrate movement into our daily lives in a realistic and enjoyable way.

What you will learn

The book explores fundamental questions: Is exercise really natural? Why do so many people avoid it? How can we make physical activity more gratifying? Throughout its pages, Lieberman reveals the evolutionary principles that explain our resistance to exercise and offers strategies to overcome it.

Among the topics covered are the evolution of the human body, comparison with other animals, the role of rest and energy expenditure, and how modern societies have transformed our relationship with movement. All with a practical and accessible approach, without resorting to miracle cures.
