GAME OF THRONES star Hafthor 'Thor' Bjornsson has wowed the internet with a crazy workout technique.
Thor is one of the strongest men in the world and he has to be creative to maintain his massive frame.
So instead of using a dumbbell to workout in the gym, he used his WIFE Kelsey Henson, 32.
With a dumbbell in his right hand, Thor held onto a belt attached to Kelsey and began lifting her up and down.
The Canadian reportedly weighs around 50kg, with the dumbbell slightly heavier, yet Thor managed 11 reps.
Fans were stunned with the video being viewed more than two million times on Twitter.

Impressed fans rushed to praise the Strongman, who has deadlifted 501kg in the past.
One fan said: "He's a tank keep up the great work."
Another added: "What a beast honestly."
