Phwoar-ty One! Chris Hemsworth shows off his buff body as he strips off following birthday surf

Chris Hemsworth showed off his muscular body on his 41st birthday.

The Hollywood star was spotted in Byron Bay, where he enjoyed the waves to celebrate his special day.

Undeterred by the heavy rain in the coastal town in northern New South Wales on Sunday, Chris stripped down in the car park.

The Thor actor had the biggest smile on his face as he took off his wetsuit and showed off his muscular body.

The star donned loose black pants but went shirtless as he mounted his surfboard to his car.

Chris kept his hair neat for his birthday and grew a light beard as he enjoyed the sea.

He also put on a black baseball cap and dried his muscular body with a blue and white striped towel.

The Hollywood hunk also had a chat with former surfer and local friend Owen Wright.

It comes just a day after the handsome actor returned to Australia from Fiji after celebrating the 40th birthday of his best friend and long-time personal trainer, Luke Zocchi.

Luke has been credited with helping Chris develop his incredible physique and maintain it into his 40s.

Chris previously paid tribute to coach Zocchi in a photo he posted on Instagram last Monday.

The actor also posted a throwback photo, showing his lithe physique from when the two men were boys.

The new photo showed how much they had grown into men, and how they had developed impressive muscles in the process.

“Happy 40th birthday to one of my best friends @zocobodypro you are one of a kind bro,” Chris wrote in the caption of the image.

Zocchi, who lives near the Hemsworth clan in Byron Bay, helps the superstar and his wife Elsa Pataky train their physiques for blockbuster roles.

Elsa, 48, used the same program Chris followed for his new blockbuster, Thor: Love & Thunder, to get in shape for her role as the muscular Captain JJ Collins in Interceptor, putting her in “the best shape of my life.”

Both Elsa and Chris used the Power program – designed by Luke – on Chris’ fitness app Centr.

Luke told FEMAIL exclusively that weightlifting is essential for anyone who wants to lose weight and build muscle.

To get your biceps looking like the God of Thunder, Luke recommends working on your upper body for the first four to six weeks of a new training regimen.

“Keep the weights manageable for yourself and the number of reps as low as possible,” he says.

‘Then I would challenge myself a little more each week: increase the intensity of the weights you use and increase the number of reps from 6-8 to 8-12.

“I would focus on two sessions of ‘pushing’ movements and two sessions of ‘pulling’ movements to make sure you are working all the different muscles you want to work.
