Switch flipped, Challenge accepted. You've conquered the chaos. Now, flaunt those All Out Mayhem shirts like a badge of honor!


What do you get when you fuse together the 1-Mile Benchmark and Orange Everest? MILE HIGH!


For Mental Health Awareness Month, Coach Kate from is getting real about her mental health journey. She's been battling anxiety and depression for as long as she can remember.​

But then she found Orangetheory. It's been more than just a job or workout—it's been her lifeline. She shares, "Orangetheory gave me purpose and passion from the minute I walked through the doors. It gave me hope during COVID. And it gave me the support system I needed when my dad died, constantly reminding me that I’m not alone and I would see the sun again."​

Being able to show up at a job every day that brings joy because it's all about spreading sunshine in others' lives—well, that's what fuels Kate. And as she watches members progress, her own flame burns a little brighter each day.

Some advice going into the 1-Mile Benchmark: You’ve written emails longer than this


This dynamic mother-daughter duo runs on Orangetheory. Their journey began when Nicki introduced her mom Cheryl to , not knowing it would ignite a bond that extends far beyond the studio walls.​

Nicki sees working out alongside her mom as more than just staying fit — it's a testament to the resilience instilled in her by the woman who raised her. She shares, “As for my mom … don’t let her kind words or age fool you; she kicks my butt every time we work out together! I love it, though, because I want her to kick my butt for many, many more years to come! OTF is helping make that possible.”​

Likewise, Cheryl finds herself continually inspired by Nicki. She takes pride in being a positive role model for her daughter, exemplifying the essence of maternal strength. Cheryl shares, “I have never felt as strong and healthy as I do now, and I have watched my daughter transform both mentally and physically. Best decision of my life!”​

Through OTF, they're building memories and strengthening their bond, one workout at a time 🧡


You’re strong. Start lifting like you believe it.


Celebrate Mother's Other Day on Monday, May 13th! Bring mom, a mom friend, or someone else you love to the studio for this special FREE class and some well-deserved self-care.

DriTri was a magical day for Tina from . As she conquered the challenges of the DriTri Strength, the presence of her family in the studio cheering her on gave her the courage she needed to make every moment feel more meaningful. ​

As she reflects on the collective journey, Tina extends her heartfelt congratulations to everyone who lent their sweat and spirit to this event. From the supportive sales associates and motivating coaches, to the all the members and their families and friends, each played an integral role in creating the DriTri experience. Regardless of their role, everyone came together, showing the power of camaraderie and shared determination. She says, “Whether it was as an athlete or spectacular spectator, we are all family and we did it together."

To the ones who continue to show up, to the ones who push harder every day — this applause is for you! 👏 Keep inspiring us all!


For Tess, completing the DriTri represented more than just crossing the finish line — it symbolized a triumphant return to herself, as it was one of her first goals after having her daughter, Mia. ​

Tess shares, "Since her, my life has changed entirely, and I thought at one point I had lost a part of who I was before having a child. But getting back into something I had so much passion for has been amazing. Thanks to my daughter, my new passion of being her mama sets the drive I have for getting back into a healthy lifestyle and building back strength."​

Through perseverance and determination, she reclaimed her sense of self, rediscovering the power of her own strength and resilience. With Mia as her driving force, Tess embraced the challenge of DriTri, emerging stronger, more empowered, and more deeply connected to the transformative journey of motherhood.


Please, for the love of all things Orangetheory, do not reset your rower today

Right before DriTri, Coach Sally from asked Ashley a loaded question: What is her why? It's a question many of us tend to overlook when confronting challenges or embracing new experiences.​

For Ashley, her why resonates deeply within the exhilarating aftermath of pushing herself beyond her comfort zone. She shares, "It’s that moment when you look back and say, 'heck yeah, I just did that!' When you push past all your limits and you grow in ways you didn’t know were possible. The nerves that always come before something big often turn into excitement after. I hold onto those feelings. That’s my why — to better myself by doing things I thought were impossible."​

To anyone who has yet to experience the DriTri, Ashley's message resounds: "Take the leap of faith and DO IT!!! It’s something I’ll always remember 🧡"

💨 Sprint: 1,000-meter row · 150 bodyweight reps · 1.55-mile run or 0.75-mile power walk
