first KEY POINT

Humans have evolved to avoid physical activity — Does that make us lazy?

Daniel Lieberman has never considered himself an athlete. He describes himself as a nerdy and small kid, struggling with anxiety connected to physical activity. If anything, he grew up avoiding physical activity as much as possible. Like many teenagers, he felt unsure and uncomfortable in his body, and, as such, sports lessons were never a fun time for him. However, he fell in love with evolution over the years and chose to learn more about it as he moved through his education and into college.There are many different myths associated with exercise. If you don’t exercise enough, you’re lazy. If you exercise too much, you’re obsessed. Many people exaggerate the amount of exercise they do. But, while exercise is certainly healthy, it’s possibly not the magic wand that many people expect it to be. It may not prevent or cure every disease alone. Lieberman questions how exercise can be the special cure for all if people these days are living longer yet are more physically inactive than ever before.

There is no denying that exercise is healthy, but to work to its optimum level, you need to eat healthily, get plenty of sleep, and cut down on stress.

Throughout this summary, Lieberman helps us understand the double standards associated with exercise. On the one hand, it’s healthy and helpful, but on the other, it’s not going to be the answer to every health issue either. By learning more about exercise and its need, you can banish any hang-ups about physical activity and find a healthy and positive route.

second KEY POINT

Genes and lifestyle are the main factors in exceptional athleticism

It’s interesting to think about why athletes are so focused and motivated. In 2012, Daniel Lieberman observed the Ironman World Championship in Hawaii — a place that focuses on tourism and enjoying the finer things in life, not particularly health and wellbeing. However, when the race begins, the participants only have their eyes on one prize — making it to the end of the course. For some, that could be in a few hours, but it would be around midnight when most cross the line.The race’s motto is “Anything is Possible,” and the participants who finished late grabbed Lieberman’s attention. What pushed them to put their bodies through such exertion? What motivated them? What did they get out of it?
