Liz Gilinger

Owner ~ Over 35 years in the fitness industry

With over 35 years in the fitness industry, I’ve witnessed countless trends come and go. Through it all, I’ve learned a simple truth—real transformation isn’t found in fads; it’s built through consistency, purpose, and connection.

When I first opened CoreFit, I started with kettlebell training. The moment I picked one up, something clicked. It wasn’t just about strength—it was about how it made me feel: empowered, capable, alive. I knew I had found something special, and I wanted to share that with others.

At the same time, my experience taught me that relying on any one modality alone can eventually lead to imbalance or burnout. True strength comes from variety, from training the body in different ways to support longevity, resilience, and overall well-being. That realization led me to expand CoreFit by incorporating multiple proven, time-tested training methods to create a more balanced and sustainable approach to fitness.

As CoreFit continued to grow, so did my vision. But after COVID, like so many of us, I saw a deeper need emerge. People weren’t just looking to get stronger—they were searching for clarity, for balance, for a way to reconnect with themselves in a world that had completely shifted.

That’s when I expanded CoreFit beyond traditional fitness and introduced energy work and 9D Breathwork. This wasn’t just an addition—it was an evolution. A way to help people release, rebuild, and rediscover their strength from the inside out.

Today, CoreFit is more than a workout. It’s a space for transformation. A place where you can challenge your body, strengthen your mind, and reconnect with who you truly are—supported every step of the way.
