Calling all strength stars: your DriTri dress rehearsal is today. 🎬 Supersets in Act 1, full performance in Act 2. Spoiler: there will be sweat. 💦 Who's ready for the real deal after that?

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.

09/01/2025

You’ve been building up to this. Every rep, every meter, every minute. DriTri isn’t just a challenge, it’s a celebration of how far you’ve come. Whether you go Full, Sprint, Strength, or Team … just know: You’re not starting from scratch. You’re starting from strength. And you’ve got tri-hard written all over you 🧡

📆 Sept 19-21. Let’s go. Register now on the mobile app or at the front desk.

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!

Today, healthspan is everywhere—in books, news articles, surveys, and popular podcasts like The Peter Attia Drive and Huberman Lab. Ever heard of it? According to a recent consumer trends report, more Americans would rather feel 25% healthier than live 25% longer. In other words, they’d prefer to prioritize their healthspan.

“Staying in shape as we age is all about consistency, variety and making sure you’re doing things that truly benefit your overall health,” Latham says. “Cardiovascular health is one of my top priorities, and I’m a big believer in the power of interval training. Functional strength is just as important, too. Focusing on building and maintaining functional strength supports everyday activities and helps prevent injuries. Incorporating multi-joint exercises into your routine can keep your body strong and resilient.”
