Jason Momoa’s muscles can’t be stopped.

The Aquaman star and all-around awesome grizzly man (he chugs beer and throws axes like it's his job) has been working out in the gym with intensity to get into shape to play the King of Atlantis, doing rope workouts, renegade rows, cable pulldowns, and dumbbell raises—and now he’s adding more moves to his repertoire.

Momoa showed off another look at his sculpted physique, this time his shredded back and shoulders as he does a climbing wall workout and some pullups in the gym.

Momoa’s muscles pop with definition as he makes the climb—make sure to watch to the end to get a great Momoa flex shot:

The former Game of Thrones star has been working non-stop over the past few years, and coming up he has a slew of fun releases.

Momoa will star in the completely wild-looking The Bad Batch—a futuristic, dystopian love story that takes place in a Texas wasteland, and he’ll get to show off his comedic chops alongside Bruce Willis as a drug-dealing gangster in the action-comedy Once Upon a Time in Venice.

Then, of course, he’ll star as Aquaman in the highly anticipated Justice League before going on his own solo outing in 2018.

Be prepared to see a lot more of Momoa—and his muscles.
