You might know Tim Ferriss from his massive bestseller "The 4 Hour Work Week." He's back with a new book, "The 4 Hour Body," and this time he's created a video to go with it that seems like a combination of blockbuster movie and Army recruiting video. Your heart rate will definitely hitch up a notch watching this and it's not like any other book video you've ever seen. So watch and tell us what you think. Compared to other book videos this is a whole different kettle of fish.

Ferriss has done something we're sure went against everybody's advice: he wrote a second book in a completely different category from his first, and he's featuring this wild trailer on the web instead of going to mainstream media. So watch and let us know what you think by voting in the poll below.
