Thor Björnsson Puts 284-Pound Dumbbell to the Test

See what happens when The 'Game of Thrones' star attempts a shoulder-blasting move with the massive weight.

Remember that brand new toy Hafthór Júlíus Björnsson AKA The Mountain proudly displayed a few days ago? We have no doubt the Icelandic strongman has been putting it to good use since getting his hands on it -- as seen in the Instagram post above where he hoists the iron beast overhead for a jaw-dropping, single-arm shoulder press.

What was the 'Game of Thrones' star's message upon completing this herculean feat? "Arnold Strongman Classic 2016! I'm coming! Here's one solid rep with my 129kg/284,4lbs THOR'S DB!" We'll certainly be on notice, as will his competition at The Arnold Classic next month in Columbus Ohio.
