Early Life & Education
Kayla Itsines was born on 21 May 1991 in Adelaide, South Australia, Australia. As of 2025, she is 34 years old, and she is the daughter of Anna and Jim Itsines, who both teach. She has a younger sister, Leah, who is also a personal trainer and food stylist.
Kayla Itsines attributes her interest in fitness to her experience playing basketball and other sports. Initially intimidated and dominated by the gym, a personal trainer encouraged her to “just start somewhere.”
She discovered that she enjoyed how the workouts made her feel, leading her to abandon her original plans of becoming a beauty therapist.
However, when we talk about her educational background, after completing her school education, Kayla Itsines graduated from the Institute of Fitness at the age of 18 as a master trainer.
Career Journey
Kayla Itsines started her career at a women’s gym in Adelaide. She noticed that many women desired smaller thighs, flatter abdomens, and toned arms.
She began training her sister’s friends for netball, focusing on core strength and legs, providing nutrition advice, and using Instagram to track progress, gaining thousands of followers.
In March 2013, Kayla Itsines and her ex-fiancé Tobi Pearce founded the Bikini Body Training company. They released the first two Bikini Body Guides in January of the following year, which included Itsines’ workouts and nutrition information from dieticians Julie Dundon and Anne Schneyder. By October of the same year, the guides had been downloaded over one million times.
The BBG program consists of 28-minute high-intensity workouts three times per week. Its 150 movements incorporate sports and other forms of physical training. Initially, the meal plans provided 1,200 calories a day, but they were later updated to provide 1,600 to 1,800 calories.
The program mainely targets women because Itsines understands women’s health and fitness goals. She describes the overall strategy as not focused on weight loss or muscle gain but rather on creating a particular look.
In 2015, Itsines conducted a world tour, the “Kayla Itsines Bootcamp World Tour,” offering free group fitness classes in various cities worldwide.
In February 2015, she filed a lawsuit against Ratcliffe and his partner, Harley Johnstone, for making defamatory comments on their YouTube channels.
To prevent the future publication of the videos, Itsines secured an injunction. Despite being directed to trial, the case was eventually settled out of court.
In November 2016, she published her first book, “The Bikini Body 28-Day Eating and Lifestyle Guide,” and her second book, “The Bikini Body Motivation & Habits Guide,” was published in August 2017.
Instead of focusing on herself and her journey, Itsines highlights her followers’ fitness journeys. She rarely posts photos of her face and carefully selects photo shoots that fit with her image.
