Just today she took to Instagram to share an insight into her training progress with her followers, and we can see why.

Model Thalia Heffernan has that most enviable of body types – tall, lean and toned – but it doesn't come without hard work.

"By eating clean, to a certain extent, and training every week day I've managed to develop my muscles in such a short time frame," she wrote on Instagram today next to two snaps taken a week apart.

The 20-year-old favours cross-training style workout sessions with her personal trainer, including a LOT of tough abs workouts.

"No sudden movements, like sneezing, for me for the next few days," she joked after a particularly intense core session last month.

And with a new sportswear campaign for Life Style Sports just launched, it's clear Thalia's hard work has been paying off.

Just LOOK at her killer abs in that crop top:

The Sports Born, Street Worn campaign was styled by Courtney Smith and features a range of brands including Nike, Adidas Originals, Ellesse and Converse. 

It's all available to shop now online at LifeStyleSports.com with next day delivery if you order before 7am – hurrah!

Among the looks featured in the new campaign is this Adidas Originals Firebird Track Top (€70) which we're thinking we might have to snap up for ourselves.

And for the man in your life, there's a whole range of seriously stylish hoodies and tracksuits, like this Adidas Originals Mens Graphic Hoody (€65) and matching Adidas Originals Pant (€55).

Now, if we could just have Thalia's abs to go with our new clothes, we'd be sorted.
