Big shoutout to our members who crushed some serious class milestones this week — your dedication is no joke! 💪 You’ve officially logged more splats than most people log Netflix episodes.

And a HUGE congrats to Nikki for completing 75 Hard! That’s some next-level discipline — we’re all inspired by you.

Keep showing up, keep pushing hard, and keep proving that consistency wins every time. Here’s to the next milestone — and maybe a few more burpees along the way. 😉

It all kicks off this Friday — are you ready to face the challenge? 💀 Each workout will push you past your limits and test your grit, but you’ll come out stronger (and maybe a little sweatier 😈).

Check out the picture below for our Hell Week dress-up themes — let’s bring the energy, the costumes, and that signature OTF spirit all week long!

Big thanks to FASTSIGNS for our new Hell Week banner!!

🏴‍☠️ Ahoy, OTF Lake St. Louis Crew! 🏴‍☠️

Last Friday, our studio turned into the high seas for Capture The Flag — and our members showed no mercy! 💪⚓️ Teams battled it out, rowed through the waves, and chased that treasured flag like true Orangetheory pirates.

Some claimed victory and the glory that comes with it, while others were left plotting their comeback for next time ☠️. No matter who captured the flag, everyone left stronger than when they boarded ship.

Who’s ready to set sail for our next workout adventure? 😈👻🧙‍♀️

The beauty of the 200m Row Benchmark? You don’t have time to overthink it. You just row. And row hard. We’re talking all gas, no brakes — blink and you’ll miss it, so don’t blink. 🚣✨

💀 It’s the most frighteningly fun time of year… HELL WEEK 2025 is coming to Orangetheory Lake St. Louis!

You’ve faced the 12 Minute Tread. You’ve survived the 2,000m Row. But can you handle 8 days of wicked workouts AND wild dress-up themes? 🎃😈🧙‍♀️

Get ready to sweat, scream, and splat your way through the spookiest week of the year.

Huge shoutout to our milestone crushers, treadmill PR-setters (hello, speed demons 🏃‍♀️💨), and our birthday legends who chose to celebrate with burpees instead of cake... or maybe both.

Y’all showed up, showed out, and probably still feel it in your glutes. We love it. Keep crushing it, OTF fam!

Meet Daisy 🌼 — the definition of consistency. A 5am regular at OTF Totowa, she’s transformed her fitness, her mindset, and her life.
​
In her own words: “Starting Orangetheory in 2023 didn’t just change my fitness — it transformed my mindset. I’ve always had the spark, but Orangetheory gave me the fire. The coaching, the staff, the community — they became the family I didn’t know I needed, and the push I never knew I was missing. Thank you.”
​
Daisy, you’re proof of what happens when you show up for yourself. We hope you’re so proud. 🧡

Today's forecast: 0.25 miles of full-send energy. It’s short. It’s sweet (kinda). And it’s your moment to go all gas, no brakes. Cue the dramatic music and fast feet. 🎬👟 don’t gatekeep the victory — drop those times 💫

09/29/2025

Btw, you’re not too sensitive. The world needs more soft hearts and more “you.” So, keep showing up with your whole heart — and taking care of it, too. 🧡

Consider this your permission slip to be that person. 📣👏 Milestones deserve a moment — so take it.

Something wicked is brewing under the orange lights … and it’s far more sinister than a few extra burpees. 🧙‍♀️ A coven of witches has crept into the studio, weaving paralyzing spells, cursing tread blocks, and stirring dark magic into every rep. It’s not just Hell Week anymore — it’s Hell Week, hexed. But their sorcery has one weakness: you. From October 24-31, take on 4 of the 8 hellishly hexed workouts to break their curse. ​
​
Register now in the mobile app or at your local studio to face the coven head on and send them flying back to their dusty old cauldron. (And yes, you’ll get a shirt — proof you lived to tell the tale.)

👏 Strong women don’t just show up — they show what’s possible. Celebrating you today and always. Happy National Women’s ...

Meet Kara — one of the incredible founding members of OTF Woodlake! 🍊
​
After stepping away to welcome her daughter in November, Kara couldn’t wait to get back under the orange lights. When she heard Woodlake was opening, she jumped at the chance to return to the workouts, the coaches, and the community she missed so much.
​
For Kara, it’s the friendships, support, and shared goals that make OTF feel like home. She’s a big fan of Tread 50 and already has her sights set on Strength 50 next! 👟🧡
​
Welcome back, Kara — we’re so glad you’re here.

National Weightlifting Day landing on Press & Squat? Coincidence? Nah. Call it fate — or perfectly chaotic programming. Today reminded us: Strength isn’t about perfection — it’s about progress. It’s the rep you didn’t think you could finish, but did. The weight you were scared to grab, but crushed. The version of you that keeps showing up. Now tell us: What’s your biggest strength win lately? 👀🏋️‍♀️

DriTri? Handled. Finish line? Crossed. Bragging rights? Forever. Thanks for bringing the energy, sweat, and all the ‘I can’t believe I did that’ moments. 🏆✨

It’s officially the first day of fall — and orange is literally the color of the season. so yeah, we’re in our prime.

09/19/2025

To everyone heading into DriTri this weekend: You’re ready. Not because it’ll be easy — but because you’ve done hard things before. And if your brain forgets that mid-burpee, don’t worry — your coach will very loudly remind you. 🧡

10/10 recommend bragging about your milestones. 💅
