Game of Throne’s “The Mountain” (aka Hafþór Júlíus Björnsson) and his twelve week old Pomeranian, “Asterix,” showed off their cardio workout on Instagram recently (see more here). Ástríkur (his Icelandic pronunciation) has over 8,000 followers on Instagram, and when Björnsson isn’t posting pictures of Ástríkur, he’s preparing for the 2016 World’s Strongest Man competition.
