"I did my research and thought it was something I could achieve but didn't quite think that big so I'm pretty happy."
But Julia says she could not have done it without her powerlifting coach Strini from Physical Impact.
"It's really hard to coach yourself as you are too close to see the big picture. He creates my programmes that generally consists of lifting four times a week as I generally do another 18 hours of gym classes ranging from body pump to body balance."
Good results could be achieved rather quickly and she wants to promote the benefits of lifting to other women.
"When I started studying to be a personal trainer I realised the majority of women like myself are into cardio, especially endurance cardio.
They are up for a jog and go and go and for many of us the main drivers are weight loss, general health and longevity."
Strength training is great for women, she says, and you can achieve awesome results.
"I've been doing it for about a year and a half. I realised it has got to be one of the best things around for women and we are just not doing it.
"It was really scary at first coming from being a runner and cyclist. In my opinion strength training offers significant benefits for women's bone density, metabolism, and mental health - it is a phenomenally empowering sport."
The vegan says lifting weights has not changed her physique. "I am not really bulky or masculine like a lot of people worry about, that is a bit of a myth. Powerlifting has really changed my life."
In the future Julia says she wants to set more records.
"Hopefully I will do more of the same and it's in the Olympics so maybe one day I will go down that path. I will just keep doing what I am doing."
