Fitness influencer Katie Austin is reflecting on five years of business growth. On March 31, the SI Swimsuit model shared an adorable duo of photos on Instagram to illustrate her progress over the last few years.

In the first snapshot, Austin posed in a hot pink workout set with a phone in her hand, which depicted the Katie Austin App on screen. The other pic was a flashback from 2018, when Austin first launched her workout app. She wore a similar two-piece athleisure set in purple.

“March 2023 vs March 2018!” Austin wrote in her caption. She then went on to share how much her business has grown in recent years.

“Running your own business let alone being your own brand is scary,” Austin admitted. “... There’s been times (and years) where I definitely felt very alone and ready to move on. I’m so so happy that I’m still creating weekly workouts, recipes, and daily schedules on the same platform all these years later.”

The 2022 co-Rookie of the Year added that it “feeds my soul” to be able to help clients achieve their best selves through the fitness and health content she creates.

“GO SIS,” fellow SI Swimsuit model Brooks Nader gushed.

“So PROUD!!!” Austin’s mother, fitness guru Denise Austin, commented. “The Sky is the Limit Baby!!!! Xoxo.”

“So thankful you never gave up!” a fan added. “You consistently inspire many to do the same, including myself post 2 babies!! Keep going 🙌🏻❤️.”
