Chris Hemsworth shows off his rippling muscles as he arrives in Sydney via private jet with brother Luke after Fijian getaway

Chris Hemsworth has just arrived in Sydney after a trip to Fiji.

The Hollywood superstar arrived at the airport in style after travelling home in a private jet.

The Australian actor was joined by his older brother Luke, 43, and Luke’s wife Samantha.

The group visited the tropical paradise to celebrate the 40th birthday of Chris’ best friend and regular personal trainer, Luke Zocchi.

The 40-year-old superstar showed off his muscular arms in a black tank top paired with black pants.

He wore a cap and looked concerned as he waited outside the terminal and made a phone call.

The brothers were accompanied on the trip by their parents, Leonie and Craig Hemsworth.

Chris paid tribute to trainer Zocchi on Instagram on 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.

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

Luke also revealed that 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 her life.”

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

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.
