Here's some motivation to go to the gym tomorrow – a World War Two veteran who may be the oldest gym junkie on the planet.
And at 98 years old, he has no plans to stop working out.
For John Hamilton age is just a number. And so is 100, the number of sit ups he does a day.
"As an old man, I want to keep myself fit," he told 7 News.

His hour-and-a-half long workout is putting other gym junkies to shame.
The ex-army major who served in the Second World War has always tried to keep in shape as the years went by.
But the "gentle" exercises recommended by his doctor became a little more serious in his 90s.

Now the nonagenarian cannot see a reason to stop or slow down.
"No I can't see it," he said
"It's what I feel, and every day I feel I want to go to the gym, it's an addiction."

"He's become part of the furniture he's been here so long, he's here like clockwork."
John said he is a living example that you are never too old to keep yourself fit.
And younger generations could learn something from him.

"I think not enough young people keep themselves fit," he said.
"I've seen men come here stay a couple of weeks then finish. Why?"
John's wife passed away a decade ago and says exercise is as much about the min as it is the body.

"If I stop exercising tomorrow, I think I'd give up life. I'd say you know, life's no longer worth living. I'm just static," he said.
"I don't think about age, I think about how I feel."
And John feels he will still be working out when he turns 100.
