Here's to the women who lift weights and spirits. 🧡 You lift each other. Your families. Your communities. And every day, you keep proving that strength comes in so many forms. Happy National Women's Health & Fitness Day! 💪

09/29/2026

At Orangetheory, we take heart health to heart. 🧡 This World Heart Day, we’re celebrating every choice that keeps your heart moving, from showing up for class to taking the stairs to getting outside for a walk. Because taking care of your heart today means more moments, more milestones and More Life ahead.

What’s one thing you do to show your heart some love? 👇

09/28/2026

Progress isn't always about doing more. Some days, your best means lifting heavier. Some days, your best means simply showing up. And every day you choose to keep going, you're building something bigger than you can see. Because growth isn't measured by one workout. It's measured by what happens when you keep coming back. 🧡

Different studios. Different milestones. One incredible community. 🧡

330+ classes. 35 pounds down. 5.5 pounds of muscle gained. A mile time improved by 1:27. 🔥 And Kenncy from OTF Coconut Creek is just getting started.

Since joining in April 2025, she’s made showing up a priority, often before most of us are even awake at 5 a.m. 😮‍💨 And the results speak for themselves. Stronger. Faster. More consistent. And proof that the work you put in, class after class, adds up.
​
Drop some love for Kenncy and everything she’s accomplished! 👏

Every strength journey starts with one brave decision: picking up the weight. Since then, you've probably surprised yourself more than once. Maybe you hit a new PR. Maybe you grabbed a heavier dumbbell. Maybe you proved to yourself you were capable of more than you thought.

In honor of National Weightlifting Day, tell us: What's your biggest strength win lately? 👀🏋️‍♀️

09/23/2026

The chips are falling into place … The Chipper is BACK. 🪓 Today, we’re chipping away at every push, every rep and every row until there’s nothing left but the finish line. Describe The Chipper in one word👇

09/22/2026

Happy first day of fall! 🍂🧡 Around here, we've always had a soft spot for orange. Pair that with cooler weather, cozy hoodies, and a community that keeps showing up, and we'd say this season suits us pretty well.
​
What are you most looking forward to this fall?

The older we get, the more our KPIs seem to change.

Maybe success used to look like checking every box. Now it looks more like feeling strong for life. Protecting your peace. Moving because you get to. Being kind to yourself.

Funny how the metrics that matter most aren't always the ones anyone else can see. What's your #1 KPI? 🧡

We’re SO excited to celebrate Kayla Gabay (Mogil) as our May Member of the Month! 🧡

After joining us in February following maternity leave, Kayla has jumped right in. With just 24 classes in 2 months she has hit the ground RUNNING! Alongside her friend and OTF Bestie Shayna, she’s been building consistency, strength, and an incredible presence in our community.

🍊 Your Proudest OTF Moment So Far?

— Completing the DriTri. My goal was to not take breaks, and it was my first time postpartum that I ran 30 minutes straight. I haven’t gone back to power walking since!

👀 What Would You Tell Someone Who’s Nervous To Try Their First Class?

— Don’t be. The only competition is with yourself. I have never been in an exercise environment more encouraging and supportive as they are in Orangetheory.

💪 If You Had To Describe Your OTF Vibe In 3 Words, What Would They Be?

— Motivation. Dedication. Energetic.

Keep it up, Kayla! 🔥🔥
