Kelly McGonigal's latest book, The Joy of Movement, is both a work of science and a love letter to the human body/spirit.

I admit, when I ordered it, I thought I knew what I was going to read: a well-researched, engaging tale of how exercise improves our mood and our brain functioning. I was delighted to be surprised by a treasure trove of ideas and philosophies that go far beyond the biochemistry of mood and movement.
