She’s Australia’s golden girl of fitness – known for her fabulous abs and enthusiasm for clean living.
And now Kayla Itsines has revealed just what goes into creating impossibly toned pins like hers.
Taking to Instagram, the star shared that she is ‘not actively trying to get a bigger booty’ or trying to build more muscle in her legs.
So what exactly do you need to do to achieve the same look?
‘I do a combination of plyometric training, weight training and LISS training to maintain what I have at the moment,’ she told her 8 million followers.
Plyometrics, also known as ‘jump training’, are exercises in which muscles exert maximum force in short intervals of time, with the goal of increasing power.
LISS, meanwhile, stands for Low Intensity Steady State cardio and is any activity that requires about 50 per cent of your maximum heart rate.
But whilst Kayla’s physique may be the envy of many, the star admits not everyone is a fan.
‘Now, this is something I’ve been wanting to say for a while,’ she shared.
‘I get a lot of comments like 'she skips leg day' or 'she needs to squat more'.
‘Honestly, to all the people that have a negative opinion, I REALLY like my legs, just the way they are.
‘I respect women of all shapes and sizes and whatever their goals are... but I am not actively trying to get a 'bigger booty' or trying to build a any more muscle in my legs.
‘So for the people telling me I need to train more, harder, or heavier,...... I appreciate your input, but I love my body how it is. I train because I love it and I LOVE how it makes me FEEL!’
Earlier this year, the 26-year-old opened up about her clean-living lifestyle – explaining to her Instagram followers why she hadn’t had a drink in six years.
'I never really liked the taste, the way it made me feel, or any of the experiences I had associated with it,' she wrote.
'I have not had alcohol in six years (almost seven) and I probably will never drink it again.
'I feel that I am a role model for a lot of young girls and I would love to show them that it's okay not to drink if you don't want to.
'I am proud to spread that message. You don't need to feel like you HAVE TO drink alcohol to fit in. You can still be social and have fun without it.'
