Food Habits
Kayla’s approach to food is simply about balance and flavor, with a healthy dose of her Greek heritage. She eats modest but hearty morning meal toast sprinkled with olive oil and baked with anchovies, tomato food, and olives, then a minute or two of Greek or Turkish mulled coffee. Snacks are simple and healthy—tuna on rice crackers, Greek yogurt with fruit, or crunchy sticks of veg with tzatziki. A quick tuna salad with brown rice and fresh veggies is frequently found at lunch, and dinner becomes a welcome family reunion, we experience too much comfort food with combined meats, salads, and roasted vegetables with bread or rice. For dessert, she often likes Greek cakes, dark chocolate, or fruit — but all in moderation. Kayla highlights that a balanced diet (without eliminating any food group) is the key and she preferred (her choice) to add healthy alternatives and even not drink alcohol.
Hobbies
Away from coaching, she can be found playing basketball on her go-to court – her “happy place.” She enjoys a good long refreshing walk with her two Siberian huskies, Ace and TJ. She is a self-proclaimed “neat freak,” and cleaning and organizing is her preferred way to recharge when it’s time for some downtime.
Tattoo
Kayla Itsines doesn’t have any permanent tattoos. She’s mentioned on social media that any tattoos you see in photos are either fake or belong to someone else. The only tattoo she’s had is a lip blush procedure, which is a cosmetic treatment to enhance lip color rather than a traditional tattoo.

Boyfriend and Dating History
Tobi Pearce (2013–2020)
Kayla initially encountered Tobi at a local Adelaide gym in 2012, where their shared passion for fitness blossomed into a friendship. While Kayla worked tirelessly to construct her growing brand, Tobi explored innovative business ventures. Their synergistic relationship led them to unite on the massively successful Bikini Body Guide digital program. Their professional bond soon transformed into romance outside of work.
By April 2018, their feelings had only intensified, prompting Tobi to propose marriage. Shortly after, Kayla delightfully declared she was with a child. The following April, they enthusiastically welcomed daughter Arna Pearce into their lives, cementing their journey together privately.
However, by August 2020, after eight blissful years as a couple and two years as engaged partners, irreconcilable differences emerged. While the specific triggers remained undisclosed, Kayla acknowledged Tobi’s laser focus on entrepreneurial pursuits diverged from her own aims. Despite parting privately, they maintained a cordial friendship and co-parented diligently as dedicated co-parents.
Even after separating, their dedication to the burgeoning fitness brand Sweat endured,uniting them professionally until its lucrative acquisition by iFIT. Their experience highlights how professional collaborations can continue thriving although personal paths diverge.
Jae Woodroffe (2022—present)
Kayla Itsines and her partner Jae Woodroffe started dating very under the radar in late 2021 or early 2022. Kayla introduced her partner and best friend Jae on social media in January 2022, and something about this love was just too adorable.
This couple had become so close by July 2022 that Kayla posted their engagement on Instagram, with a few happy images and an image of her engagement ring. It resonated with Jae, too, as he said in a heartfelt post of his own that, sometimes, you just know.
Kayla rings in another chapter in her love story in December 2023, saying ‘The most perfect day ever with my husband Jae.’ They now combine family life with their son, Jax Stokes Woodroffe, born in January 2023, and Kayla’s daughter Arna Pearce from a previous relationship.

Net Worth 2025
$140 million
As of March 2025, it’s estimated that Kayla Itsines has a net worth of about $140 million. She isn’t just another fitness influencer—she’s a powerhouse entrepreneur who turned home workouts into a multimillion-dollar business. With a mix of relatable personality, effective workouts, and smart business moves, Kayla has built a global brand from scratch. But how exactly does she make her money? How much has she earned from each venture? Let’s break it down.
The Sweat App – Her Biggest Moneymaker
At the heart of Kayla’s business success is the Sweat app, a fitness platform she co-founded in 2015 alongside her former partner, Tobi Pearce. What started as a set of PDF workouts known as the Bikini Body Guide (BBG) quickly evolved into a full-fledged mobile app offering high-intensity workouts, meal plans, fitness programs, and community support—especially for women.
-
In 2020 alone, the Sweat app generated $99.5 million in revenue.
-
In 2021, Kayla and Tobi sold Sweat to iFIT Health & Fitness for a reported $400 million.
-
In a surprising twist, Kayla and Tobi bought back the Sweat brand in late 2023, reportedly for much less, though the exact amount hasn’t been made public.
The app is simple, effective, and beginner-friendly. No gym needed. Just your phone, a yoga mat, and some motivation. That’s the charm—it fits into real life.
Social Media Sponsorships
With over 16 million followers on Instagram, Kayla has a massive online presence. She’s not just followed—she’s trusted. Her followers admire her for being real, honest, and no-nonsense.
-
$26,000 to $35,000 per sponsored post
-
If she does just one sponsored post per week, she could be making over $1.5 million annually from Instagram alone.
She only promotes brands that align with her values—no gimmicks, no sketchy diet pills. That kind of authenticity keeps followers engaged and sponsors happy.
Fitness Merchandise and Equipment
Kayla has extended her brand into the world of fitness gear. From resistance bands to foam rollers and water bottles, she sells everything a home-workout lover might need.
While exact numbers aren’t public, fitness brands of her scale often generate millions per year. For Kayla, this likely adds another 7-figure revenue stream to her business.
People who use her workouts trust her recommendations. Her name on the label = instant credibility.
Books and eBooks
Before her app became globally famous, Kayla was already making money through her BBG eBooks. These PDF guides were the foundation of her fitness journey, helping thousands of women get fit from home.
Later, she released printed books and cookbooks, combining fitness tips with healthy recipes.
Her digital BBG guides alone earned millions during the early years. Book royalties continue to bring in passive income.
The guides are clear, simple, and results-focused. Perfect for people who want to start their fitness journey without feeling overwhelmed.
Real Estate Investments
Kayla has also made smart moves in real estate. In 2017, she bought a luxurious home in Malvern, Adelaide for $3.9 million.
In 2024, she sold it for $7.375 million, turning a $3.475 million profit—just from property appreciation.
This shows that Kayla isn’t just investing in fitness. She’s growing her wealth through property too—like any savvy entrepreneur would.
Brand Collaborations
Aside from fitness-specific promotions, Kayla partners with brands that align with her lifestyle. Whether it’s wellness, beauty, or tech, she chooses partnerships carefully.
Brand partnerships can range from $100,000 to $500,000 per campaign depending on the deal.
Her clean, health-focused image makes her a favorite among premium lifestyle brands.
Personal Brand – Kayla Herself
It’s important to note that Kayla is the brand. She doesn’t just sell workouts—she sells a lifestyle. She’s a mom, a businesswoman, and someone who values authenticity. People connect with her story, which adds value to everything she touches.
She earns indirectly through:
-
Speaking at fitness expos
-
Media features
-
Podcast interviews
-
Magazine covers and interviews
All of this boosts her profile, which circles back into revenue through her core businesses.
