Chris Hemsworth shows of his muscular physique as he turns up the heat in Australia and goes surfing

Chris Hemsworth showed off his toned physique on Monday as he turned up the heat in Australia and went surfing on the beach.

The Marvel star, 39 – who recently enjoyed a family holiday in Bali with his gorgeous wife Elsa Pataky – was back in his hometown of Byron Bay, where he turned heads with his spectacular body.

Hemsworth strolled shirtless on the beach, baring his plump biceps and muscular abs.

The Thor star wore black swimming trunks and a matching ball cap, had a tight scruff on his face and a sun-kissed tan.

Chris also caught some waves during his relaxing day at the beach, and he looked incredible carrying surfboards under each sculpted arm.

The A-lister stays in phenomenal shape by sticking to a strict workout regimen and following a high-calorie diet.

Hemsworth kicks it into high gear for a movie, as his longtime stunt double, Bobby Holland Hanton, 37, recently testified to his intense physical preparation before taking on a role.

Chris pushed Bobby to the limit in the final movie in the Thor franchise, giving his stunt double just eight weeks to build up for Thor: Love and Thunder.

In a recent interview with Ice36Hanton described the grueling demands placed on him, saying he told the star, “You’re kidding!”

Bobby had to pack on nearly 22 pounds of muscle and consume 4,000 calories a day for him to transform into a convincing Thor.

“I ate up to 10 meals a day, two of which were protein shakes,” Bobby shared with Ice 36. “We (he and Chris) worked out twice a day and I never in my life thought I would be sick of food and not want to eat, because I like to eat.’

But the film industry veteran, who has worked with the Australian-born superstar for 15 years, says the training regimen was a real test.

“I hated it,” he said. “I ended up trying to give away food that I had to eat because I just didn’t want to eat it. It almost made you feel sick because you were never hungry.”

Pain and Gain: Speaking of his preparation for Thor: Love & Thunder, Hemsworth said in the Marvel documentary Assembled that “it was just exhausting.” Calling his transformation “extremely difficult,” he added, “I don’t know, maybe I’m getting old, but things just started to hurt more” (Hemsworth pictured in Thor: Love and Thunder)

Speaking of his preparation for Thor: Love & Thunder, Hemsworth said in the Marvel documentary Assembled that “it was just exhausting.”

Calling his transformation “extremely difficult,” he added, “I don’t know, maybe I’m getting old, but things just started to hurt more.”

In an interview with USA today to promote the film last year, Chris revealed his lifestyle during the Covid lockdown: ‘It was train, eat, train, eat. Nothing else to do. Then I came for the movie bigger than I’ve ever been.’

But his wife Elsa Pataky didn’t like the extra muscle, as Chris said she called it “too much,” echoing the couple’s girlfriends: “There are a lot of my male friends who say, ‘Yeah!’ but a lot of female friends and family are like, “yuck.”‘
