Peter Stefanovic works up a sweat as he goes for a run in Sydney

He no doubt has his hands full after welcoming his first child, son Oscar, with wife Sylvia Jeffreys back in February.  

But on Friday, Peter Stefanovic managed to take some time out to enjoy a solo jog around his Sydney neighbourhood. 

The 38-year-old cut a casual figure as he worked up a sweat during the strenuous run. 

The journalist wore a grey Pearl Jam T-shirt with red, white and blue striped Nike shorts. 

He completed the look with a red cap, which he wore backwards, and a pair of grey sneakers. 

During the workout, Peter appeared to be listening to music with a pair of AirPods. 

At one point during the workout, Peter took a break and slowed down to a stroll to catch his breath.  

The television reporter’s workout may have been influenced by his brother Karl Stefanovic, who recently embarked on a weight loss challenge. 

The Today show host promised to lose 10 kilograms in 10 weeks while interviewing obesity expert Dr Nick Fuller back in May.

Last month, the 45-year-old proudly revealed on the breakfast program that he’d weighed himself at home that morning and had shed an impressive eight kilos.

The Channel Nine star, who recently became a father for the fourth time, admitted it had been tough finding the time to exercise but said he was feeling ‘great’.

‘In the last couple of weeks it’s been difficult with the baby and all that sort of stuff,’ he said, referring to his youngest daughter, Harper May.

‘It is life getting in the way of it a little bit, but it’s been a fantastic program,’ he added, thanking Dr Fuller, who had supported him throughout his journey.
