  • 30 Most Influential People on Social Media by TIME magazine in 2016


“I hope that women all around the world feel encouraged and supported. I hope that through the photos and stories I share, they realise there is no perfect body, no right or wrong way to be, and that everyone is different and that’s okay.”

“I genuinely love chatting to and learning about the women who use my programs, so it’s never a bother.”

“Social media has been key to reaching so many women all around the world. Each country uses different social channels, so it’s important for me to be present and posting in different ways to reach as many people as possible.”

“One of my favourite tips for women at all points on their journey is to start small. If you don’t feel like going to the gym, just hop on the treadmill or a bike for 10 minutes.”

“Sometimes that first step is the hardest, but once you’ve taken it, you will find your stride.”

“It’s a common misconception that you need to work out for hours everyday to see results, and it’s also really hard to find time for anything more.”

“I encourage my clients to listen to their bodies. If you’re feeling really tired, schedule a rest day, if you feel like getting your blood pumping, try a HIIT session. Do what feels right for you.”

Kayla Itsines began hitting the gym for health reasons but found it enjoyable and made it her career and helping others women to get a healthy body.
