As part of our ongoing bodybuilding awards month - this week Jessenia Vice is comparing the top 5 bodybuilding backs we nominated for 2017.

It makes sense - as seeing a truly wide and mammoth back can leave a real strong impression. Who do you think has the best back of the year? Watch the episode of This Or That above and then cast your vote in the YouTube comments to decide the ultimate winner!
