While some are taking advantage of their time in lockdown to rest, The Block’s Scott Cam has a different approach and has been taking advantage of his home gym.

The 57-year-old surprised fans with his new muscular frame on social media last week, explaining that he’s using his home gym to get fit before The Block hits TV screens later on this year.

"Training hard in the cave gym during isolation," the Gold Logie winner wrote.

"Trying to counteract my beer intake.”

Cam has raised eyebrows in recent years, saying that once he hit 40, he’s “woken up the size of a doona”.

"I've tried to stay fit and healthy, I don't mind a beer," he once said.

"But as you get old the metabolism slows down and you struggle to keep the weight off."

Cam has been keeping fit in isolation, and fans are impressed with his progress.

“Get it Scotty, earn those beers!” one fan commented.

Others were thrilled he was using his home gym.

“You finally finished your cave gym Scotty. I seen you on telly putting the flooring down for it. Looks great!” they said.
