THE F STANDS FOR FUNCTIONAL TRAINING, A MIX OF CIRCUIT AND HIIT STYLE WORKOUTS GEARED TOWARDS EVERYDA

Born in Australia, F45 is the revolutionary training system changing lives around the globe. The concept is simple: our studios all over the world offer a 45 minute High-Intensity, Circuit Training workout class for our studio members. We have developed 27 different 45 minute workouts, with more currently in development. Our studios offer the same class at different times throughout the day. Every day throughout the week offers a different 45 minute workout. The workouts are created by the F45 Athletics and Peak Performance Department from a database of over 3,000 different exercises, so our members never get the same workout twice.

1000 classes for Theresa! ⭐️🎉

Our 6am crew knows her well! Theresa (T) crushed her 1000th class at F45 Central Boulder this morning, and we couldn’t be more excited to celebrate her!

T is the definition of consistency. She’s always showing up, putting in the work, and keeping our early morning classes entertaining with her humor and tell-it-like-it-is personality. 😂

T, thanks for being authentically YOU and bringing so much fun and dedication to our F45 community. It’s members like you who make this place so special!

Here’s to 1000 classes down and many more early mornings together! ❤️💪

Outside of F45… 👀

We’re engineers, artists, new moms, accountants, nonprofit leaders, mitigation specialists, professional athletes, public health professionals—and so much more.

Different careers. Different backgrounds. Different stories. One place we all come together!

That’s one of our favorite things about this community. For 45 minutes, titles get left at the door. We show up, work hard, cheer each other on, and get stronger together. We’re more than a gym. We’re a community. 🫶

So… what do YOU do outside of F45?

Today, we welcomed the man, the myth, the legend, Bill Moltner to the 1,000 Club! 🎉👊

Bill was presented with his custom Nike Metcons before taking on a spicy workout — because 1,000 classes definitely calls for a celebration🔥

Bill founded our studio back in 2018 and handed over the reins to our new owners a year ago. We love when we get to see him in the studio, lifting heavy, putting in the work, and crushing life outside of F45 😊
