Chris Hemsworth celebrated the end of filming for the fourth "Thor" movie by showing off his massive arms in a new photo.

The photo was taken by Jasin Boland, a still photographer for the film. In the caption, Hemsworth hyped up the movie and joked about not flexing his muscles.

"That's a wrap on Thor Love and Thunder, it's also national don't flex day so I thought this super relaxed photo was appropriate," he wrote.

Thank you to all the cast and crew who made this another incredible Marvel journey. Buckle in, get ready and see ya in cinemas!! @taikawaititi @marvelstudios 📷 @jasinboland."

The actor's post caught the attention of friends and fans, many of whom commented on his ripped physique.

Stars like Jeremy Renner, Dwayne Johnson, and Jason Momoa - who portray Marvel and DC Comics superheroes - congratulated Hemsworth on wrapping the film.

Simu Liu, who will star as the titular character of Marvel's "Shang-Chi and the Legend of the Ten Rings" (in theaters on September 3, 2021), said: "Jesus Christ I need to get in shape."

This isn't the first time people have marveled at Hemsworth's muscles.

Recently, the actor posted a photo of his large arms - but all people could focus on were his legs, which looked much skinnier in comparison.

Costar Natalie Portman previously described Hemsworth's body as "otherworldly," while Chris Pratt jokingly told the actor to "stop working out" since they're going to be in the same movie.

Hemsworth made his Marvel debut as the God of Thunder in 2011's standalone "Thor" movie. Since then, the Australian actor has reprised his role for two sequels and several "Avengers" films. Most recently, he played Thor in 2019's "Avengers: Endgame."

The end of the blockbuster film paved the way for the upcoming "Thor" movie by hinting at Hemsworth's character teaming up with the Guardians of the Galaxy.

"Thor: Love and Thunder" is currently set for release on May 6, 2022 and will feature the return of several Marvel stars.

Portman, who stars as an astrophysicist and a love interest named Jane Foster will be wielding a hammer.

Tessa Thompson will reprise her role as Valkyrie and, according to the actress, her "first order of business" as the king of New Asgard is to "find her queen."

Lady Sif actress Jaimie Alexander will also return as Thor's friend from the first two standalone movies.

And Christian Bale, known for his role as Batman in Christopher Nolan's trilogy, will join the cast of "Thor 4" as a comic-book villain named Gorr the God Butcher.
