Kayla Itsines Easy No-Equipment Abs Workout

Fitness entrepreneur Kayla Itsines has shared the simple, no-equipment exercise regimen she follows to maintain her taut torso. 

The mother-of-two, 35, took to Instagram on Tuesday with a series of videos demonstrating the six abdominal exercises, along with a simple breakdown of the routine in the caption. 

Clad in a tiny purple crop top and matching bike shorts, the bronzed brunette showcased her rock-hard abs as she effortlessly ran through each exercise: a single leg ab bike, straight leg jack knife, alternate single leg raises, controlled mountain climbers, reverse crunch and hip lift, and a plank rock. 

'No equipment. These are the six ab exercises I keep coming back to,' she wrote, noting that fans should aim for 30-40 seconds of each exercise and perform the entire routine for four rounds. 

'SAVE THIS! Your core will thank you later,' the Sweat app founder added alongside a winking emoji. 

Fans were quick to heap praise on the super-fit influencer, with one commenting: 'You make it look so easy', while another cooed: 'I love your workouts!'  

It comes after Kayla raised eyebrows after she shared her unusual shower habits. 

Posting to Instagram in December, Kayla revealed that she has several non-negotiables when it comes to her hygiene routine. 

'I don't want to say OCD without getting properly diagnosed, but I won't leave the shower if I don't brush my teeth twice, wash my face twice and wash my body in a certain order,' Kayla began.

Kayla added she needed her full concentration when doing so to prevent a distraction, which would make her go back to square one. 

'If anyone distracts me or I forget how many times I have done it, I have to do it all over again,' she wrote.

'Yeah, that's where I'm at, haha.'  

Kayla first shot to fame more than a decade ago with her Bikini Body Guide e-book.

This evolved into the internationally successful Sweat fitness platform, which she co-founded with her ex-fiancé Tobi Pearce.
