I know, I know, I know. I should exercise more. And this book points out the many ways it benefits not only your body but also your brain. I enjoyed this book, surprised that it was not just another “shoulda been an article but I beefed it up into a book” type book. I think what saved him was the inclusion of so many stories, of patients, or of research papers and studies. He gets pretty technical, and you learn some stuff about the old noggin, like the fact that serotonin, dopamine, and norepinephrine are all neurotransmitters.
It starts out strong, with two examples of schools that boosted their test scores by implementing a new way to do gym, that of focusing on heart rate for participation, not just performance. Exercise gets the blood flowing, gets your brain fusing new pathways, gets you ready to learn. Chapters touch on stress, anxiety, depression, and specific changes that women go through monthly and then through menopause. Throughout it all, a drum beat to get 5 days of exercise of 30 minutes at a minimum. This is just the safe side. Best? 6 days a week, 45min to an hour, four days longer with moderate intensity and 2 days shorter with higher intensity.
