And from a video shared to Instagram by Cody, it wasn’t your average gym session…

In fact, the unlikely fitness rivals took part in a fitness challenge against each other to see who could reach the highest RPM (revolutions per minute) on a pull-down machine.

While at 44-years-old, dad-of-three Karl is twice the age of 22-year-old Cody, he gave the singer a run for his money win the fitness stakes!

Karl kicked off the challenge and was seen furiously pulling on the weights for several seconds before reaching an RPM of 637.

It was then Cody’s turn, but he was no match for the controversial TV presenter.

“He’s not gonna get there! He’s not gonna get there!” Karl was heard jeering in the background.

He then added, clearly pleased with himself: “Eat my s**t, Simpson.”

Karl has shared details of his health and fitness journey with fans in the past. 

Taking to Instagram in November he told fans he was making some changes to his lifestyle after taking the advice of a doctor. 

“I was told a little while ago by a doctor I needed to make some changes to my physical health,” he shared to his Instagram. 

“It’s been tough. I was fatter than I thought. Ha. But I’m getting there. Slowly. I want to thank @osher_gunsberg for the inspiration.

“And @emiliebrabonhames and @chiefbrabon for making me bleed. Its been really positive. For anyone out there I truly believe it’s never too late,” said Karl.
