After 8 days of Hell Week, today you call the shots. Base Day or All Out Day … what’d you choose? ⬇️

What happens in Hell Week doesn’t stay in Hell Week. Especially when you earned the shirt to prove it. 🔥 Hell Week 2026, you were weird, wonderful, worth it, and officially in the books! Now show off that shirt in the comments. 👇

10/31/2026

If we’re going out, we’re going out in a Blaze of Glory. 🔥 Day 8 of Hell Week. Halloween. One final workout. 🎃 Nobody’s finishing this one alone. 30 nonstop minutes of Tornado chaos, distances to chase and a team beside you pushing toward the finish. One last time. Let’s raise some hell. 🤘

10/30/2026

100 here. 200 there. Bragging rights everywhere. 🧡

SMOKE RISES AND SO DO YOU! Way to rise to the occasion and crush Hell Week Day 5! 🔥

10/30/2026

There are no wrong choices today. There are also no easy ones. 💀 Day 7 of Hell Week is here and just like that, all hell breaks loose. Pushes that test how long you can hang on, your choice to lift more or row more and burnouts waiting around every corner. Decisions, decisions. 🤭

10/29/2026

The fire’s already burning. Time to add fuel. ⛽ Day 6 of Hell Week is Fuel the Flames, where every rep and every 3-minute challenge adds a little more to the fire. The reps keep climbing, the recovery gets shorter and the flames only get bigger. 🔥

10/28/2026

Hell Week Day 4 is in the BOOKS. Did you feel the fire with the choices you made on the treads and the rowers?! Comment if this was your Day 4 of 4! Let’s see who has already earned their t-shirt! 👀💪🏻

10/28/2026

Where there’s smoke, there’s Hell Week. 💨 Day 5: Smoke Rises brings elevation gains to chase, switches that keep you moving and a burpee that builds piece by piece. Buckle up, it’s about to be a whirlwind. 🌪️

Some things are bigger than a workout. 💗 This Breast Cancer Awareness Month, we’re celebrating Coach Jenna, her health and the community that showed up beside her through it all.

Jenna’s Orangetheory Mt. Prospect family came together at the Lemons of Love 5K to honor her and everyone whose life has been touched by breast cancer, a reminder that the strength we build together reaches far beyond the studio.

Here’s to Jenna, to good health and to every person who has fought, supported, remembered and kept showing up. We’re so grateful to celebrate this chapter with you, Coach. 🧡

10/27/2026

You asked, and we heard you! 🙌 The 5 AM class is BACK on the schedule this week, Friday, 10/30! 🔥
Now let’s show up and FILL THAT STUDIO! 💪 We can’t wait to see you bright and early for day 7 of Hell Week, South Riding! 🧡🖤💀

Hell Week Day 3 ✅ Did you feel like you were in the hot seat?! Those froggers sure made the legs burn!🔥

10/27/2026

You know what they say about playing with fire. 👀 Day 4 of Hell Week is all about one thing: blazing the legs from start to finish. Tread more or row more, the choice is yours. And with mini bands in the mix, there’s no escaping the heat. Good luck, legs. 🥵

10/26/2026

Pick your poison. You’re in the hot seat either way. 🔥 Day 3 of Hell Week brings the burn with big rows, distance on the tread and reps that come with a catch. Choose wisely. The burn is finding you no matter what. 😮‍💨

10/26/2026
