Vikings is one of the hottest shows on television—and we can't say we're surprised.

The History Channel's wildly popular series has everything you could possibly want in a historical drama—legendary heroes, bloody battles, and some of the fittest dudes in the business. The male stars of Vikings are muscled-up, and could easily take on anyone in a barroom brawl. (They are portraying Norse warriors after all).

This, of course, begs the question: Of the most fearsome, ridiculously jacked actors on the show, who is the most ripped of them all?

And that prize, in our opinion, goes to Alexander Ludwig. Not only does the 25-year-old actor play Bjorn Ironside, the son of the fabled Norse king Ragnar Lothbrok, he's got a warrior-worthy set of six-pack abs in real life.

Here are seven photos, straight from Ludwig's Instagram account, which prove that he's the fittest dude on Vikings.
