Nicole Gallagher never realised how much she "let herself go" until she looked back on photos from a girls' weekend away.

The Aussie mother-of-two was on a weekend trip to Forster, a coastal town in New South Wales, just over a year ago when she was faced with a person she didn't recognise — herself.

"My friends and I had always been around the same size and it wasn't until I looked at the photos when I was like, 'Oh my God'.

"I had let myself go so bad. They are all size 8s and I was a size 20."

It was in that moment the 34-year-old, who weighed more than 90kg at her heaviest, decided to change her lifestyle. And she did just that, transforming from a size 20 down to a happy 8-10 in just six months.

"It was super-confronting and tough. I just didn't want to be that woman anymore," Gallagher told

"I had ups and downs with my weight, but I was never that heavy. With my first child [now 7 years old] I got close to 80kg, but this time, with my second child [10 months], I really blew out and let myself go."

Gallagher suffered from postnatal depression (PND) with her youngest child and was also recovering from a broken arm after falling down a flight of stairs, which she said contributed to her weight gain.

"I didn't have PND with my son, it was a whole new feeling with my little girl. I put so much pressure on myself. I thought, 'I should know what I'm doing', having had one before.

"My brain was really playing tricks on me and I couldn't understand, being a devoted mother, why I felt this way."

Knowing she had to take control of her life again, Ms Gallagher joined a local gym last November. Once she started clean eating and training her journey to happiness and contentment began.


She signed up to a six-week challenge and won. She also came first in a national competition through the gym and went on to win AU$5000 — she was judged on her weight loss, before-and-after images and overall lifestyle changes.

"I never want to be that overweight, depressed woman again. She's just somebody I used to know," Gallagher said.

She had never been a "gym person" and signing up was daunting.

She started with three sessions a week.

"It broke me. I had no form and also suffered from ab separation after giving birth. I was in agony and I wasn't lifting correctly — I wasn't shown how to do things correctly."

One of the mothers from her son's school introduced her to another gym where she took part in group workouts.

"Since then I haven't looked back," she said.

Gallagher now goes to the gym six days a week, mainly before school drop-off at about 4am.

She started seeing results after two weeks — a body scan showed her visceral fat (the fat around the organs) had also dropped.

"It added years onto my life. Then I started to notice I was dropping numbers on the scale and also my measurements, and I wanted more."

Her workouts consist of weights, endurance, strength and conditioning and high intensity classes.

"I feel like a whole different person. I've totally transformed and changed my life. I just never want to go back to that person. I feel like I am a better wife and mum with more energy for my family."

Her words of advice for anyone looking to improve their lifestyle is not to listen to that "inner b**ch telling you, you can't do it".

"If I can do it, you can do it … the world is yours."
