The statistics about the draw weight of war bows being 100 to 170 lb (45-77 kg) is striking to me. Imagine getting to the gym, picking up a single 45 kg dumbbell (the lowest end!), and setting out to rep as many single-arm rows as you can before failure. Of course you wouldn't hold that dumbbell at full contraction; that would be insane and you'd gas out in seconds.
