A 67-year-old Australian grandmother is going viral after stepping onto a national bodybuilding stage alongside competitors decades younger and walking away with the over-60 title.

Jan Herdman has captured attention across social media after footage of her recent win attracted more than half a million views in a matter of days, with many Australians stunned not just by the result, but by the physique she brought to the stage.

Competing against women in their 20s, 30s and 40s, Herdman’s appearance and confidence have struck a nerve online, tapping into growing conversations around ageing, fitness and what strength can look like later in life.

“I walked in with doubt in my chest,” Herdman said.“Every other competitor was younger. I told myself, just do your best. And somehow, that was enough.”

Challenging ideas around ageing

Herdman, an age-transformation coach, personal trainer and three-time Mrs Australia physique champion, said she only discovered strength training at 40, following a difficult period in her life.

Nearly three decades later, she is still competing and says the reaction to her latest title reflects a broader shift in how women want to approach ageing.

“I want people to understand this. Your body is not done with you. Not at 50. Not at 60. Not at 67,” she said.

“But you have to stop waiting for the perfect time to start.”

Herdman said competing against younger women was part of the reason she entered.

“I am old enough to be their grandmother. That is exactly why I am doing it,” she said.

Viral bodybuilding moment sparks emotional response

The internet reaction has been swift, emotional and at times humorous.

Among those responding was Bianca Dye, Herdman’s former Golden Bachelor co-star, who commented: “OMG DAT ASSSSS”.

Others focused on the confidence and courage required to step on stage.

“You were a winner the moment you stepped on that stage,” one follower wrote.

Another added: “Amazing. Well done. You are so brave to put yourself on stage.”

For many women watching, the moment appeared to resonate far beyond bodybuilding itself, becoming a symbol of resilience, reinvention and refusing to quietly fade into the background with age.

Strength training among older women rises

Herdman believes the response reflects a growing appetite for different conversations around ageing and health.

“The women I work with every day make a choice,” she said. “They stop shrinking. They start showing up. And they transform, not just physically, completely.”

She said the emotional response to the viral footage suggests many women are recognising parts of themselves in her journey.

“If something stirred in you when you saw that, that is not a coincidence,” she said. “That is the version of you that has been waiting.”

Despite the growing attention, Herdman insists she is not trying to be viewed as extraordinary.

“I am not trying to be special,” she said.

“I want this to be normal. I want women in their 50s, 60s and 70s to know they can still build strength and feel incredible.”

At 67, she says she is only getting started.
