Natural Born Heroes is a good one. Basically, there is a an overview story about a kidnapping of German officer during World War ll on the island of Crete, and how the kidnappers survived and what they ate and how they bounded through the mountains with ease and how some elite British Special Forces were trained and what they did to train to be a top notch group. And that is interesting, but the real good stuff is the research that McDougall does about a high fat diet, the primal (my term) way that we are meant to move ( he interviews knife throwers, Parkour practitioners, Steve Maxwell), and the application of all of those things to a modern lifestyle. Those chapters are what I found most interesting. And then in Outside Magazine, McDougall has a webpage with articles and videos related to the book that are worth a look. http://www.outsideonline.com/
Music? If you are into country music that has zero rap influence and zero fakeness to it, check out Whitey Morgan and the '78's.
Morgan is Waylon Jennings reincarnate, and sings with feeling and an outlaw state of mind, as does Chris Stapleton. Here is Stapleton on Letterman:
Stapleton has a knack for great hooks and also has not sold out to the new Nashville sound of pop country crap.
For some country music that is in the vein of Hank Williams jr., check out Frank Foster. If you are going out hunting or fishing or just sitting on the bumper of a pickup on a dirt road swapping stories with friends and a cooler, Frank is your man.
As for some more upbeat, thrash, training music, check out Kreator. Thrash to get you going.
