Meet Natasha from OTF Estero 🧡
For Natasha, More Life isn’t just about milestones — it’s about moments. The ones where she’s running side by side with her son. Laughing. Moving. Living fully.
She never imagined she’d run 50+ miles during Marathon Month or complete the DriTri — but she did. She pushed beyond what she thought was possible.
“By challenging my body in ways I didn’t think I could,” she says, “I’ll be able to keep running and playing with my son for a lifetime.”
Because every rep, every step, is building a lifetime of moments that matter most.

Since joining Orangetheory Lawrence in September 2024, Andres has been on a mission to live a more active, balanced life — and he’s doing just that.
Originally from Costa Rica and now studying supply chain management and accounting at KU, he’s juggling workouts, recovery, and academics with heart and hustle. His favorite part of OTF? The community. Because nothing beats the kind of motivation that comes from pushing through a tough block side by side with friends.
Since starting, Andres has gained strength and built muscle, and he's now working toward bouncing back from a knee injury — one step at a time. All with Timber on blast and the Jayhawks in his corner. 🏀
We’re cheering you on every rep of the way, Andres!

OTF Forest Acres wouldn’t be the same without Lauren! Since 2018, she’s brought nonstop dedication — in the studio, at home with her two kiddos and husband, and on walks with her Bluetick Hound, Remy 🐾. Thanks for showing up, shining bright, and inspiring us all! 👏

She’s not for the weak — 2000m Row Benchmark: equal parts petty and painful. May your legs be strong and your lungs be stronger. How’d you do? 👇😮💨
