Karl Stefanovic, 50, has shocked his social media followers after showing off his newly ripped physique following a major body transformation.

Karl Stefanovic has showed off his impressively ripped physique in a hilarious new video at the gym following a major body transformation.

The Today host, 50, has been open about his weight loss journey after once tipping the scales at 105kg back in 2020.

Stefanovic later told The Kyle and Jackie O Show that unflattering paparazzi photos taken at his heaviest prompted some stern advice from his billionaire pal James Packer.

“James Packer sends me a note that says: ‘mate, you need to get your a**e to the gym’,” Stefanovic said.

On Friday, Stefanovic shared a comedic video to Instagram which showed him working out with friend Peter Oreb while his personal trainer Mark Glanville danced in the background.

The veteran Channel 9 star and father of four performed a series of gruelling push-up exercises in the clip as his biceps noticeably rippled beneath a tight orange tank top.

“There’s something not quite right about my trainer,” Stefanovic captioned the video, which featured the song “I Wanna Dance With Somebody” by Whitney Houston.

Fans of the Today host flooded the comment section to praise his new rock hard physique.

“Brah when did Karlos get muscles,” one fan wrote.

“Karl got guns,” another supporter said.

“You got a licence for those firearms?!”

“Whatever he’s doing it’s working,” another fan agreed.

Meanwhile, Stefanovic’s sister-in-law Jade Yarbrough raised her concerns that Stefanovic was working out in the gym shoe-less.

“More concerned about you not wearing shoes in the gym again,” she wrote.

The video was quickly picked up by Today producers, who used the video of their star presenter’s workout for a segment about “Dad Bods”.

Stefanovic’s body transformation comes months after reports the Today star is currently vying to replace Rodger Corser as the host of top-rating gameshow The Floor.

The quiz show, which sees contestants challenge each other in head-to-head trivia duels, has proven ratings gold for Nine in the 7.30pm time slot ever since it premiered in April.
