farmers walks

Since I live in a rural area, a carry things more than an average person, I guess. Mostly a lot of water jugs. Recently, I just tried out some official "farmer's walks" with dumbbells. Various weights. Various distances. I'm  very curious what other people think of this exercise, if they do it, what weight they hold, and how far they walk, etc.

My grip is good, so mostly what gets tired on me seemed to be my upper traps. Everything had to stay pretty tight while I was walking though. What is this exercise supposed to improve? Has anyone attributed this exercise to some beneficial result, after doing it regularly?
