When he signed up for The Block, losing weight and getting fit was the last thing on his mind. But, as those kilos continue to fall off him, Brad admits his continued weight loss has been a happy by-product.
"I don't know how much I've lost as I never weighed myself before," he admits. "But I think about 10kg. My clothes fit better and I'm down a few notches on my tool belt, and a few notches on my normal belt."

"My boardies are falling off me now!" he says with a laugh. "I may even lose some more."

"I think it’s all the manual labour," Brad explains.
"And when we realised Brad was losing weight, we started eating much healthier," Lara adds.
Although her partner's clearly reaping the rewards of their new, hectic lifestyle, Lara says she hasn't been quite so lucky.
"I've put on 3kg!" she laughs.
"Yes, but not now I'm making you project manager for the week — it will be falling off you," Brad laughs.
Lara doesn't look quite so convinced.
