Check out the “Body for Life” book by Bill Phillips at the Library. It will get you into great shape for the pack test. It helps with setting and measuring goals, strength training and cardio fitness.
I read “Young Men and Fire”, “Fire on the Mountain”, “Fire in Their Eyes” and “Fire Line” this winter. They were all very good books. The reviews are on the firebooks page with a link to Amazon.com (the site gets a referral fee if you buy through this link).
While I have no aspirations to dig line, I like to be able to carry on an intelligent conversation when I ask my friend “How was your day?” This winter I plan on taking the basic fire behavior class.
