Itsines announced she had become the sole owner of Sweat — the workout and meal-planning app she co-founded — which has over 1 million active monthly users. She had previously sold it to iFIT and later repurchased it.
The property purchase marks a high-profile real estate move following her Sweat reacquisition and broader wealth diversification strategy.
Fortune spotlighted how Itsines diversified beyond fitness after the $400M Sweat exit, citing an unconventional gas station investment as one of her first income-generating moves.
As a co-founder of Sweat, Itsines joined a Snowflake-hosted session at the NRF Retail's Big Show to discuss how data and AI are reshaping customer engagement and brand growth.

Kayla Itsines is an Adelaide-based personal trainer who built one of the most recognizable women's fitness brands globally through Instagram before the platform's algorithm favored video. She began personal training in 2008 and developed the Bikini Body Guide (BBG), a structured circuit-training program that gained viral momentum through community-posted transformation photos shared under a unified hashtag movement. That community eventually grew into the Sweat app — a subscription workout platform that has reached tens of millions of women worldwide. Her approach consistently frames physical training as a route to confidence and mental resilience rather than aesthetics alone, a positioning that has helped her retain cultural relevance well beyond individual program cycles.
Itsines operates primarily on Instagram, where her following spans the United States, Australia, the United Kingdom, and Canada. Her content mix — HIIT workouts, low-impact training sessions, family moments, and motivational messaging — balances professional authority with personal relatability. With YouTube uploads becoming infrequent and TikTok remaining a minor channel, Instagram is clearly her core distribution engine. Her brand equity is closely tied to the Sweat ecosystem, positioning her more as a fitness entrepreneur with creator-scale reach than a conventional influencer — a distinction that makes her particularly attractive to wellness, apparel, and lifestyle brands seeking sustained partnerships with a founder-led audience rather than a purely content-driven one.
Kayla_Itsines reaches an audience concentrated in Australia primarily through YouTube, and is best activated via long-form YouTube integrations, Instagram Reels and Stories, TikTok branded content. Their sponsorship history skews toward Fitness / Tech, a clear signal of fit for brands in those categories. Demonstrated partners include Sweat. Engagement on YouTube runs around 1.8%, which points to an audience better suited to category-relevant, mid-funnel campaigns than to pure-reach buys. The channel's mix of long-form YouTube integrations and Instagram Reels and Stories lets a sponsor choose between short awareness placements and longer, more detailed integrations. Because the audience follows fitness content rather than arriving through untargeted reach, sponsorships that match the channel's subject matter tend to convert more efficiently than broad placements. A consistent, on-topic posting focus gives sponsors a predictable, brand-safe environment, lowering placement risk compared with broad, general-interest channels. Campaigns here are best measured on qualified engagement and consideration within the niche rather than on raw impression volume. For Australia-focused brands in Fitness / Tech and related categories, Kayla_Itsines offers a defined, creative-fit audience rather than broad, low-intent impressions.

BBG, or Bikini Body Guide, is Kayla's signature 12-week high-intensity resistance training program that went massively viral in the mid-2010s, largely through transformation photos shared on Instagram.
