Meet Australia's Instagram fitness queen who's about to make it big in America

She's only 23, but Kayla Itsines has already become a household name in the Australian fitness community and she's about to take the U.S. by storm.

The personal trainer and health guru has amassed over 2.3 million followers on Instagram where she posts workout moves, recipes, fitness tips, and inspirational messages.

But unlike competing fit-stagrammers who have built their audiences by posting selfies of their seemingly unattainable bodies, Itsines is all about accessibility. Her message is that anyone can lead a healthier lifestyle and through social media and her online fitness guides, she wants to help them take the first step.

She's now on an unofficial global fitness world tour that will be culminate in a trip to America this spring.
