Social media star Kirsten Too Sweet says her online fame exploded after she won Crunch Fitness’ viral #CrunchBooty Instagram contest — a win that scored her $1,000 and massive internet recognition.
Known online as @kirstentoosweet, Kirsten was crowned the nationwide contest winner in 2023 after submitting just one photo of herself stretching on a foam roller at the gym.
The post, tagged with “#crunchbooty,” quickly went viral and grabbed the attention of Crunch’s corporate team, who shared it across multiple franchise social pages.
“Once they posted it to all their social accounts for each location, I gained a following and heard from tons of brands,” Kirsten shared. “That’s when I started taking my fitness journey seriously — and growing the biggest booty.”
The viral photo helped Kirsten build a loyal following and inspire countless others to start their own fitness journeys.
Crunch Fitness later shared a follow-up post officially naming her the winner and encouraging more members to enter future contests. This year’s edition, #CrunchBooty2025, offers the same $1,000 prize and runs through August 31. Members are urged to share gym photos with the hashtag — though locker room content is strictly off-limits.
Since her big win, Kirsten has grown her social media following into the millions, using her platform to promote healthy weight gain and body positivity.
“Fitness has completely changed my life — not just physically, but mentally too,” she said. “I want to show people, especially women, that it’s okay to take up space, to gain weight in a healthy way, and to feel strong in your body. If I can inspire even one person to feel confident in their own skin, then I’ve done something right.”
Her journey highlights how niche contests can be a powerful launchpad for aspiring fitness influencers.
“Keep those posts coming,” Crunch wrote in its winner announcement, “for a chance to shine on our socials.”
