About Our Owner
Julie Curtsinger
Owner / Instructor
Fitness has been a passion of mine for nearly three decades. My journey began in competitive bodybuilding, where I earned 1st Place at the Kentucky State Bodybuilding Championships in 1998. That same year, I became a certified personal trainer through the American Council on Exercise (ACE).
In 1999, I founded and opened my first fitness facility with a partner, beginning a career dedicated to helping people become stronger, healthier, and more confident.
In 2009, I launched Julie’s Boot Camp, creating a program centered around accountability, community, and results. I later became CrossFit certified in 2012, continuing to expand my experience and knowledge in the fitness industry.
Today, I am proud to bring that experience to St. Clair Fitness, where my goal is to create more than just a place to work out. I want to create a community where people feel welcomed, encouraged, and supported, whether they are taking their very first step into a gym or have been working out for years.
Outside of fitness, I am a mother, a Realtor with more than two decades of experience, and I work in healthcare at Frankfort Regional Medical Center. Those experiences have taught me something I believe strongly: health, strength, and confidence affect every part of our lives.
You don’t have to be fit to walk through our doors.
You just have to be willing to take the first step.
Come as you are. Start where you are. Let’s get stronger together.
About Our Instructors
Laura Smith
Group Fitness Coach
I’ve been passionate about fitness for the past 5–7 years and have been training with Julie for the last three. During that time, I’ve developed a strong understanding of proper form, functional movement, and macro-based nutrition, and I love helping others build confidence both inside and outside the gym. I enjoy coaching classes and helping members feel confident, supported, and challenged while meeting them where they are in their fitness journey. My goal is to create a positive, encouraging environment where everyone can grow stronger and have fun.
Fun Fact: Outside the gym, I’m a mom to an amazing 13-year-old daughter and love making handcrafted candles in my spare time. I’m always working on a new scent or creative project when I’m not at the gym
