Barre3 instructors will challenge you to find your edge while creating space for you to define what success looks like for you in every workout.
I joined Barre a few months ago. I was always curious but thought my not so great knees would be a problem. Well... I love it and every instructor gives so many modifications for everyone. I am mad I waited so long to try!!!! The most amazing instructors😁 It is a little gem of a spot in historic St Charles!!!!

Barre3 has been the only place where I’ve been able to keep a consistent workout routine. It’s such a supportive environment through any season of life, which helped me stay healthy through pregnancies and postpartum and in all my everyday movements as a mom!
