Everyone knows that Hafþór 'Thor' Björnsson, AKA Ser Gregor 'The Mountain' Clegane, is one beast of a man but that wasn't always the case as this photo that's been unearthed from his basketball days ten years ago shows.

If you weren't familiar with the work of the 6 foot 9 inch strongman, here he is in full beast mode deadlifting weights up to a whopping 410kg.

 

Deadlift weight increases each rep by 20kg/44lbs Starting weight 270kg/594lbs - 410kg/902lbs

But before all that, back in 2006, he was playing basketball for K.R. Basket Reykjavík in his homeland of Iceland. It's hard to believe that A. He's only 27-years-old, and B. This is what he looked like ten years ago.

What a difference some (okay, a lot) of weights make...
