AFL WAG Alex Pike, 44, shows her incredible weight-loss transformation

Nathan Buckley’s new girlfriend Alex Pike has reached WAG superstardom in just a few months, eclipsing the likes of Nadia Bartel and Bec Judd.

And the 44-year-old cosmetic nurse sent her Instagram followers wild on Thursday by showcasing her body transformation in before and after photos.

Alex shared an undated photo of herself in a loose-fitting beige dress, which she contrasted with a recent glamour shot in a figure-hugging LBD.

Now and then: Australia’s most talked-about WAG Alex Pike, 44, showed her incredible weight-loss transformation in before and after photos on Instagram on Thursday

She appeared to have a fuller figure in the ‘before’ photo, although it’s hard to tell because her dress concealed her frame.

The ‘after’ photo showed the mother of three looking trim and terrific in a slinky designer frock and seductive stockings.

The picture was from a modelling shoot Alex did earlier this week. 

Before and after: The businesswoman has been open about her face and body transformation over the last two years, which she credits to the viral #75HARD Challenge

Alex captioned the transformation post: ‘Work hard.’

The businesswoman has been open about her face and body transformation over the last two years, which she credits to the viral #75HARD Challenge.

The extremely strict health and fitness challenge is described as a ‘mental toughness test’ which pushes participants through 75 days of rigid diet and rigorous exercise. 

Turning back the clock: Alex is also a fan of Cosmelan treatments, which reduce the dark spots caused by melanin, hyperpigmentation and ageing

It involves twice-daily workouts, calorie counting, a clean diet with no cheat meals, reading non-fiction books every day and much more.

Even before embarking on #75HARD, Alex followed a very clean and restrictive diet to stay in shape.

In 2016, she said she doesn’t eat any sugars, breads or pasta, and prefers resistance training and bodybuilding to aerobics exercises.

‘After having three children I am in the best shape of my life. I owe this to Isagenix shakes twice a day a dinner of lean protein and green based vegetables,’ she said. 

In addition to diet and exercise, Alex has also had many cosmetic tweaks.

Although Alex doesn’t appear a day over 25, the WAG revealed on a podcast in March that she was actually ‘close to 44’. 

‘I’ve never been more empowered in my life and I’m close to 44,’ she said on the Curious Conversations podcast.

‘I used to hide my age and be very ashamed because there’s such a stigma for women.’
