Shane Warne's son Jackson took to social media over the weekend to show off his buff physique.

The hunky 25-year-old shared a snap in which he can be seen posing alongside a friend at a recent bodybuilder event.

In the picture, Jackson looked as fit as ever, wearing a snug-fitting black casual shirt and matching pants that showcased his bulging biceps and pecs. 

He was accompanied by his bodybuilder friend, Gabriel Chenkov-Shaw, who wore a first-place medal around his neck and exposed his buff physique.

'Well done bro,' Jackson captioned the frame. 

It comes after Jackson hinted at a career move earlier this month after sharing a gallery of photos to social media which captured him posing with SAS Australia star Ant Middleton, 44, at an exclusive event in Sydney.

The pair were all smiles in the sweet picture which showed Jackson giving a thumbs up to the camera as he posed alongside a beaming Middleton.

In the caption, Middleton hinted that Jackson, who previously appeared on the Channel Seven reality TV series in 2020, may be making a return to the show.

'Sweating it out with my man Jackson Warne! Prepping for an SAS Australia All Stars,' Middleton joked.

Another picture showed the pair beaming brightly as they posed with a wax figure of Jackson's late father Shane Warne at Madame Tussauds in Sydney.

'The bros,' Jackson wrote next to the photo.

Last year, Middleton opened up about his close friendship with Shane Warne's son Jackson.

The SAS Australia star told the Mental As Anyone podcast the pair share a close bond.

'I talk to Jackson a hell of a lot,' We've had some good heart to hearts. Jackson is a man of few words, he is more introvert than extrovert,' he said.

'We've built up a special relationship and it's one that… we're definitely going to grow old together so yeah, I'm looking forward to it.'

The British star added that Jackson wants to be around 'positive' influences after the tragic death of his father.

'This is why it's so important to surround yourself with positive people, people that make you feel better about yourself, make you a better person, that give you that energy or that comfort,' he said.

Legendary cricketer Shane Warne died aged 52 from a heart attack while on holiday in Koh Samui, Thailand.

Jackson recently revealed he chose to honour his father's memory not with sorrow, but with a dedication to health and clarity.

He wanted to demonstrate a healthier way to cope with life's hardships, including going alcohol free, especially after experiencing the immense loss of his beloved father.

After his father tragically died, Jackson said he could've let his grief ruin him.

Instead, he decided to focus on his health, and to channel his trauma into 'energy for life' and was delighted with how much progress he made.
