Glamour couple Itsines and Pearce founded Sweat in 2015 and continue to work together in the business despite ending their engagement last year.

The Sweat women’s health and fitness app has engaged with millions around the world, generating estimated revenues of $100 million per year.

The platform offers more than 5000 unique workouts across 26 exercise programs ranging from high-intensity interval training and strength to yoga, barre and Pilates.

Itsines and Pearce will continue to lead the Sweat business in their existing roles, with the company remaining headquartered in Adelaide.

Pearce, who was an InDaily 40 Under 40 winner last year, said he looked forward to working with the iFIT leadership team to accelerate Sweat’s global expansion.

“iFIT enables us to create a breadth of engaging new content to fulfil the rapidly growing fitness needs of our members around the world,” he said.

Itsines said the acquisition represented a new chapter in the company’s history.

“Sweat has had an incredible journey from our humble beginnings training women one-on-one in my Adelaide backyard to launching the Sweat App in 2015 to now joining the iFIT family,” Itsines said.

“Sweat was founded on our simple belief that fitness can genuinely help women improve their confidence, health and quality of life.

“Through iFIT’s strategic leadership, we will be able to create new world-class fitness content and product experiences to support more women on their fitness path forward.”

Sweat has built a global community of more than 50 million women across its social channels offering support and inspiration to help women reach their fitness goals.

The Sweat app is translated into eight different languages and is available in 155 countries.

Based in Logan, Utah, with offices in Paris, Shanghai, Melbourne, and Manchester, iFIT says it offers immersive, adaptive, personalized workout experiences for a variety of fitness levels.

Its high-profile trainers include American swimming superstar Michael Phelps, the most decorated Olympian in history.

iFIT CEO and Founder Scott Watterson said the two founder-led businesses were highly complementary and the acquisition extended iFIT’s market reach into new geographies, demographics and fitness preferences spanning both home and commercial markets globally.

“We have a shared vision of helping people around the world achieve their goals for health and well-being,” he said.

“We are delighted to welcome Kayla’s authentic fitness training and charismatic personality—along with all of Sweat’s other star trainers—to the iFIT family.”

“The addition of Sweat will allow iFIT to further expand our membership base as well as add new fitness genres and modalities to our fast-growing subscription business, giving our company a tremendous competitive advantage.”
