That’s a WIN, team.
We’re beyond proud to be voted USA Today’s #1 Best Gym, and we wouldn’t be here without every member of our OTF family (yes, you). We already know Orangetheory is so much more than a gym — it’s about time everyone catches on 🧡

🚨 MEMBER SPOTLIGHT 🚨
Everyone, meet Rachel and Grayce! Two of our most dedicated and positive members.

They show up consistently, push hard in every class, and always bring great energy. Whether it’s their effort on the floor or the way they brighten the room just by walking in, these two truly represent what OTF is all about.

If you haven’t met them yet, make sure to say hi next time you see them. You’ll be glad you did!

Stop booing yourself off the stage before anybody has a chance to see you perform – learn to be excited about the unknown instead of fearing it.

With so much love (and a few tears), we’re getting ready to say goodbye to our amazing Coach Misty as she begins a new chapter in Ohio 🧡

Misty has been so much more than a coach to us. She’s been a true friend, a constant source of encouragement, and a bright light at Hamilton Mill. Her energy, kindness, and unwavering support have touched every one of us, and it’s hard to imagine the studio without her. West Chester, you’re about to welcome someone truly special.

Join us to give her one last sweaty hug during her final classes:
📅 Monday: 5:00, 6:15 AM
📅 Tuesday: 4:30, 5:45, 7:00 PM
📅 Wednesday: 4:30, 5:45 PM
📅 Thursday: 4:30, 5:45 PM

Let’s fill the studio with love and gratitude, reminding Misty just how much she means to all of us 🧡
