“Thor: Ragnarok” star Chris Hemsworth has one of the most enviable bodies in Hollywood, and the actor even beefed up his exercise regimen when he reprised his role as the Norse god of thunder for Marvel.

To give fans a glimpse of the intense workout he endured for the character, the actor shared a video on Instagram showing him training with “flat out legend” Luke Zocchi. Hemsworth was topless while training, showing off his spectacular abs. In the clip, he can be seen switching from bikes, battle ropes, to dumbbells, among many other things.

Hemsworth’s Thor has a different look for this third film. Before, he was known for his long, golden locks, but they decided to chop Thor’s hair off this time around.

According to Entertainment Weekly, Thor will battle with Hela (Cate Blanchett) in the beginning of the movie, but he loses to her so he gets tossed to Sakaar, a barbaric planet ruled by the Grandmaster (Jeff Goldblum). Thor is spotted by Valkyrie (Tessa Thompson), who turns him over to the Grandmaster. He is then forced to become a gladiator and cut his hair, as well as learn how to fight without his hammer.

In the gladiator arenas, Thor will be reunited with his fellow Avenger, Hulk (Mark Ruffalo). Whereas Thor is a newbie, the Hulk is different and has even come to terms with his rage. “He’s much more of a character than the green rage machine you’ve seen in the Avengers movies,” Ruffalo said of his character. “He’s got a swagger. He’s like a god.”

Meanwhile, Benedict Cumberbatch’s Doctor Strange will be making a cameo in the movie, and he will team up with the main players to face off against intergalactic villains “both familiar and new.”
