The First 20 Minutes: Surprising Science Reveals How We Can Exercise Better, Train Smarter, Live Longer

The First 20 Minutes: Surprising Science Reveals How We Can: Exercise Better, Train Smarter, Live Longer - Gretchen  Reynolds There were two main messages I got from this book:1. Exercise is really good for you in almost every way. Except when it isn't.2. You should pretty much do what feels right.An engaging overview of recent studies in exercise science, this isn't the how-to book the title suggest; it doesn't give precise info on how to exercise and how much. There's some contradictory information, which can be confusing and frustrating. Also, it was sometimes hard to tell who the given information applied to. But there's useful debunking of many exercise myths and some very thought-provoking discussion of the effects of exercise (and inactivity) on the body and mind as they age. I'd write a longer review, but I'm off to the gym.
