A 3-year-old with a six pack is well ahead of those with resolutions to tone up in 2016.
Canberra woman Ursula Meagher says she first noticed her son, Dash, was naturally muscular when she was changing his nappy.
She told Daily Mail Australia: "He curled his feet up towards the sky and I saw it and sent a picture to his dad saying 'do you see what I see?'
"He's too young to realise he has [a six pack] of course, but he's already incredibly muscly and just loves to exercise."
Meagher added her young son's love of exercise came from his love of the outdoors.
"He's outside every day, come rain or shine. I used to run with him in the pram when he was a baby, and as soon as he hit two, I took him out on what I thought would be a gentle jog.
"Dash ended up running four kilometres!"
Today, the Herculean toddler, who was conceived with IVF, has his own Instagram account.
Posts exhibit Dash's active lifestyle, depicting him swinging from a jungle gym and jumping on a trampoline – his favourite activity.
