'The Mountain' announces retirement from strongman competitions

Hafthor Bjornsson's strongman career has come to an end.

The 31-year-old, who played "The Mountain" on HBO's "Game of Thrones," announced his retirement after winning Iceland's Strongest Man title for the 10th straight year.

"Maybe I'll never return, but never say never, right," Bjornsson wrote on Instagram. "I'm still only 31 years old and could come back in (a) few years if my heart wants it!

"Right now, my heart tells me that I need to be healthy for my family and do what's best for them!"

The announcement comes a little over three months after Bjornsson set a new world deadlift record by lifting 501 kilograms (1,104 pounds). He'll now focus his attention on his upcoming boxing match against fellow strongman Eddie Hall.
