Kayla Itsines shares the ‘game changing’ planking hack she discovered after giving birth

Fitness queen Kayla Itsines has shared the ‘game changing’ planking hack she uses to make the most of her workout.

In a post to her Instagram on Thursday, the 29-year-old co-founder of exercise app SWEAT revealed the controlled breathing technique she uses when executing the exercise.

The mother-of-one said she discovered the method after giving birth to daughter Arna Leia Pearce, who she shares with ex-fiancé Tobi Pearce, in April 2019.

‘This is an absolute game changer,’ Kayla said in a minute-long video to her account, where she was seen taking her followers through the exercise.

‘You can do this no matter where you are right now… I want you to tense your muscles, and in this position, right there, I want you to watch my stomach really closely.’

In the plank position, Kayla proceeded to breathe in through her nose and rapidly breathe out through her mouth, while tensing her core. 

‘OK, so here I am pushing away from the floor, and I’m in my normal plank position,’ she explained. ‘This obviously gets quite boring and your just staring at a timer.

‘What I want you to do right now is breathe in through your nose and when you blow out through your mouth I want you to do it so hard.

‘Now, if you’re watching this video right now, you can see what just happened to my core.

‘I learnt this after I had Arna and it’s been so game changing for me. My core is so engaged. It’s so on… It makes your planks go so much faster and it is so much more effective.’

Kayla’s post follows her announcing her split from Tobi on Instagram on August 21 after eight years together.

The former couple, who share daughter Arna, created global fitness empire SWEAT, which is estimated to be worth $696million.

They put their five-bedroom home in Adelaide on the market in September, but the ad has since been taken down.
