Query: GREAT!

Didn't think this would be motivational, I thought I could "guess" what it would say, but it TRULY IS motivating! There is enough insight and inspiration to make this a worth while read. You'll be surprised how much you get out of it, definitely a book to keep on your shelf for when you're waning and not feeling like exercise is worth the time and energy ;)
