Writing from both the cutting edge of scientific discovery and the front-lines of elite athletic performance, National Magazine Award-winning science journalist Alex Hutchinson presents a revolutionary account of the dynamic and controversial new science of endurance.

Our ancestors crossed deserts, mountains, and oceans without even a whisper of what anyone today might consider modern technology. Those feats of endurance now seem impossible in an age where we take comfort for granted. But what if we could regain some of our lost evolutionary strength by simulating the environmental conditions of our forbears? Investigative journalist and anthropologist Scott Carney takes up the challenge to find out: Can we hack our bodies and use the environment to stimulate our inner biology?

Are stars like Usain Bolt, Michael Phelps, and Serena Williams genetic freaks put on Earth to dominate their respective sports? Or are they simply normal people who overcame their biological limits through sheer force of will and obsessive training? In this controversial and engaging exploration of athletic success, Sports Illustrated senior writer David Epstein tackles the great nature vs. nurture debate and traces how far science has come in solving this great riddle.

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.

Imagine this (go ahead, it's an easy one): You're bored with your workouts. Nothing's changing; you're not getting stronger or leaner or feeling better, and, heck, maybe you'll just take a layoff and see what happens. You know what happens. That two-week layoff lasts a year, that's what happens! Now consider this: Traffic was light and you're 15 minutes early for your dental cleaning appointment. You flip open your device and bring up your new copy of Before We Go. By the time the dental tech calls you, you've heard two chapters and are amped to get to the gym. Your mind is racing through the appointment, and it's all you can do to stay in that squeaky lounge chair.

Primal Endurance shakes up the status quo and challenges the overly stressful, ineffective conventional approach to endurance training. While marathons and triathlons are wildly popular and bring much gratification and camaraderie to the participants, the majority of athletes are too slow, continually tired, and carry too much body fat respective to the time they devote to training. The prevailing "chronic cardio" approach promotes carbohydrate dependency, overly stressful lifestyle patterns, and ultimately burnout.

Obstacle course racing, which combines the endurance challenges of a marathon with the mind-bending rigors of overcoming obstacles along the way, is taking the world by storm. At the center of this phenomenon is Joe De Sena, the driving force behind the enormously popular Spartan Race. De Sena offers a simple philosophy: commit to a goal, put in the work, and get it done.

That the average adult spends 50 to 70 percent of their day sitting is no surprise to anyone who works in an office environment.

In Get Up!, health expert James A. Levine's original scientific research shows that today's chair-based world, where we no longer use our bodies as they evolved to be used, is having negativeconsequences on our health.

Finally, the solution to the number-one reason we don't exercise: time. Everyone has one minute. A decade ago, Martin Gibala was a young researcher in the field of exercise physiology - with little time to exercise. That critical point in his career launched a passion for high-intensity interval training (HIIT), allowing him to stay in shape with just a few minutes of hard effort. It also prompted Gibala to conduct experiments that helped launch the exploding science of ultralow-volume exercise
