Growing up with a sister, sometimes you can’t help but compare yourself. But when your older sis happens to be one of the biggest fitness stars on the planet (ahem. Kayla Itsines), you think it’d be tough right? Well, not for Kayla’s younger sis, Leah.

Happy Birthday Sis @kayla_itsines ❤️

The 22-year-old (who is a well-known healthy foodie with 367,000 followers) recently wrote on Instagram the answer to a question she gets asked constantly: “Do you ever find it hard having a different body type to Kayla’s?”

“Of course, when I get compared it’s hard at times, but Kayla and I have COMPLETELY different body types,” she wrote. “I will never look like her, she will never look like me… Just as I will never look like you, and you will never look like me!” Preach it, sista.

“We can’t compare ourselves to other people because they are NOT US. I focus on being the best possible version of me, and that’s being super fit so I can keep up with her, super happy and with some damn naan bread in my hand.” We’ll happily share some naan with you, Leah.

I got a question the other day…which I get ALL the time! I'm not offended by much, so I'm happy to answer it here 😁 The question was "do you ever find it hard having a different body type to kayla's?"…. OBVIOUSLY this lovely girl had no bad intentions with that comment – I completely understand….kayla is daaaaaamn ripped 😂 Of course, when I get compared its hard at times, BUT – kayla and I have COMPLETELY different body types. I will never look like her, she will never look like me….just as I will never look like you, and you will never look like me! We are ALLLL different and have things that makes us OURSELVES. We can't compare ourselves to other people because they are NOT US. We have to focus on being the best possible version of ourselves, because that's in the end what matters. I focus on being the best possible version of me, and thats being super fit so I can keep up with her😜, super happy and with some damn naan bread in my hand 😂🙏🏼

If everyone could heed this advice and stop comparing themselves to each other, the world would be a very happy place!
