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


“I hope to encourage and support women around the world. I hope that through the photos and stories I share, they will understand that there is no perfect body, no right or wrong way to be, and that everyone is different and that’s okay.”

“I really enjoy chatting with and learning about women who use my programs, so it never hurts.”

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

“One of my favorite tips for women at every stage of their journey is to start small. If you don’t feel like going to the gym, go on the treadmill or bike for 10 minutes.”

“Sometimes that first step is the hardest, but once you take it, you’ll find your way.”

“It’s a common misconception that you have to work out for hours every day to see results, and it’s really hard to find time for anything else.”

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

Kayla Itsines started going to the gym for health reasons but found it enjoyable and made it her career to help other women achieve healthy bodies.
