“Game of Thrones” actor Jason Momoa, who also played Conan the Barbarian in the 2011 remake, revealed his secret for keeping his body in tip-top shape. SEX.

Momoa — who recently chopped his trademark locks — was out in NYC last night when we started talkin’ gym habits … specifically, how do you stay in shape … CrossFit? Pilates?

“I f*ck a lot” … Momoa said.

UPDATE: I removed the ‘Game of Thrones Spoiler’…. My bad.

FYI: His lucky wife is ‘The Cosby Show’ actress Lisa Bonet.
