Why else would be be staying in such good shape?
Game of Thrones star Jason Momoa shared a picture of himself as his new film Justice League wraps up.
The man who plays Dothraki warlord Khal Drogo in the HBO series is rounding off his new role as Aquaman in the highly-anticipated DC film.
While there's a wrap up party going on for the cast and crew after shooting finished in London, Momoa won't be partaking.
Along with the incredibly toned picture of him, he posted a message explaining his absence thus...
'There's to many people to thank for all their hard work JL. Tonight is our wrap party,' he wrote.
'I am so thankful for my cast and crew. I love you. I have never in my life missed a wrap party But as you all know I'm a huge fan of the food and merriment!!!!
'Unfortunately I prepare for the north. For those that will be there. I WON'T let you down.'

Fans seized upon his words almost immediately - in particular the bit where he mentions 'The North' which many took as a huge Game of Throne reference.
There is already a big fan theory that Khal Drogo will be making an epic comeback in Season Seven of GoT.
Yes the warlord husband of The Mother of Dragons, Daenerys Targaryen might have snuffed it some time back, but that's not stopped the creators of the show before.
He could be trolling us all hard, but it's barely a week since he shared this photo with Kit Harington aka Jon Snow saying 'back to work'.

And then before that he was photographed out partying with the showrunners David Benioff and D.B. Weiss at a bar in Belfast, Northern Ireland, where parts of GoT are filmed.

It's certainly not beyond the realms of possibility that Khal Drogo could make a reappearance in some form during the seventh series.
Cast your minds back to Season Two and you'll remember that Drogo did appear in Dany's visions in the House of the Undying, so there's no reason why this couldn't happen again as she stakes her claim to the Iron Throne in Westeros.
Don't rule it out.
