🌟 MEMBER SPOTLIGHT: 500 CLASSES! 🌟

Today we’re celebrating an incredible milestone—500 classes! 🎉💪

Kathy Bhat fitness journey started with a simple but life-changing conversation with her doctor. At 52, she decided it was time to make a change and took that first step into fitness. That decision led her to TNT CrossFit, and when those doors closed, she found a new home at F45.

“I was lost when TNT closed. The F45 family made me feel welcome—even when I was confused! 😂 Less confused now, and I appreciate the challenge each workout brings.”

That’s what F45 is all about. It’s not just the workouts—it’s the people who make you feel like you belong from day one.

When asked why she’d recommend F45, her answer says it all:

“There is something for everyone at every level of fitness. And it’s fun!”

Congratulations Kathy on 500 classes! Thank you for showing up, trusting the process, and being such an important part of our F45 family. Here’s to the next 500! ❤️🔥

🔥 WHY CARDIO & HYBRID DAYS MATTER 🔥
Your F45 schedule is designed with purpose. Strength days build the foundation, while cardio and hybrid days help maximize performance, health, and results.
💪 Strength Training Benefits: • Build and preserve lean muscle • Increase metabolism over time • Improve bone density • Build strength for everyday life
❤️ Cardio & Hybrid Training Benefits: • Burn more calories during workouts • Improve heart and lung health • Increase endurance and energy levels • Improve insulin sensitivity and blood sugar control • Support long-term fat loss
One of the biggest advantages of our cardio and hybrid workouts is HIIT (High-Intensity Interval Training).
🔥 HIIT creates the afterburn effect, known as Excess Post-Exercise Oxygen Consumption (EPOC). Even after your workout ends, your body continues working to recover, helping you burn additional calories for hours afterward.
The result? More efficient workouts, improved fitness, and long-term results.
Ready to get the most out of your training week? Don’t skip cardio and hybrid days! 👊

Today, several of our F45 coaches took on a triathlon, and every single one of us crossed that finish line.

Not because we’re the fastest. Not because we’re the strongest. But because this community has taught us how to show up, stay consistent, and keep going when things get hard.

*Coach Cam Coppelli | Christ, Wife, Kids | STL is super human and crushed the long coarse. Cam you are inspiring!
*Coach Liz Lara Mirth just a year off a full knee replacement, did the sprint coarse and finished 1st in her age group.
*Coaches Jasmin Mayer and Megan Rea also did the sprint coarse battling it out in the same age group. Megan crushed the swim and Jasmin flew in the run, finishing 1st and 2nd in their age group!!!

We are incredibly grateful for the support, encouragement, and friendships that F45 has given us. The confidence we carry into challenges like today is built inside these studio walls, one workout at a time.

Thank you to every member who inspires us daily. We may wear the coach shirts, but this community pushes us just as much as we push you.

So proud of our team today, and so thankful to be part of something bigger than fitness. ❤️💙🫶🏼

“This is what F45 is all about—community, accountability, and proving to yourself that you can do hard things.”

The day after a holiday is one of the hardest days to show up.

The food was good. The desserts were worth it. The routine was interrupted. The alarm clock felt extra cruel this morning.

But then…you showed up.

Not because you “had to earn” yesterday’s meal, but because this is what you do. You choose consistency over perfection. You understand that one holiday doesn’t define your progress—just like one workout doesn’t either.

Walking through those F45 doors the day after a holiday is a win all by itself.

Our community never ceases to amaze me. We laugh together, sweat together, encourage each other, and remind one another that showing up is always the hardest part.

To everyone who rolled out of bed and made it in yesterday…you should be proud. Your future self is already thanking you.

That’s what makes this community so special. ❤️💙🤍
