With just about 27 months left before the release of ‘Aquaman’, Jason Momoa is killing it in the gym and giving us a front row seat. The ripped star who also played Khal Drogo on HBO’s Game of Thrones is getting his body in tip-top shape for his heavily-tatted (and shirtless) Atlantean costume.

This past week, Momoa posted a handful of videos working out with his trainer Mark Twight, who also helped Henry Cavill get in shape for his role as Superman. One video in particular shows him doing an impressive 88-pound weighted pullup. Another one of his videos advises to not try this at home. Challenge accepted, Aquaman!
