Feeling out of breath? Karl Stefanovic, 44, works up a sweat with actor Rodger Corser, 46, during a gruelling gym session in Sydney
He's reportedly been working furiously to lose weight as he attempts to relaunch his TV career.
And Karl Stefanovic certainly threw himself into training on Wednesday as he worked out with celebrity trainer Chief Brabon in Sydney.
Former Today presenter Karl, 44, looked somewhat out of breath during the gruelling session with actor Rodger Corser, 46.

Karl kept things casual for his workout session, wearing a black polo shirt and navy and black jogging pants.
He completed the look with white trainers and a black and white basketball cap.
Stefanovic's workout comes after The Sydney Morning Herald claimed he has gotten in shape in time to shoot the second part of his series, This Time Next Year.

The publication also claimed Karl completed a staggering 65 interviews over seven days for the show, which finished shooting in March.
While Karl has another two years left on his contract with the Nine Network, it is unclear what his next move will be now that shooting for This Time Next Year has wrapped.
There have even been rumours that the journalist would anchor a late-night news show in competition to Channel Seven, however those claims were 'shot down by network bosses', the Sydney Morning Herald reported recently.

Karl's bank balance is also healthy, as he has reportedly retained his $2 million pay packet from Channel Nine.
An insider recently told The Sunday Telegraph that Karl will get the massive sum of money for just 'one week's work' fronting This Time Next Year.
'Nine are yet to announce what else they'll do with Karl this year, so as of now, he's getting an eye-watering $2 million for one week's work,' the insider said.
Karl's head was the first to roll during Nine's Today show bloodbath late last year.

The former Today host was dropped from the breakfast program during his honeymoon with Jasmine Yarbrough - now Stefanovic - in December.
With the show on an unending downward spiral in the ratings since 2016, it was believed that a new line-up of presenters would help resuscitate the program in the eyes of viewers.
However, the ratings nightmare has continued unabated for Nine, despite the appointment of Deborah Knight as co-host of Today alongside Georgie Gardner and new talking heads Brooke Boney and Tom Steinfort.
