About Us

Originally founded in 2012 in South Carolina, our mission has always been to help individuals achieve their fitness goals through functional small group training programs and nutritional guidance.

We offer a variety of group classes, including 24/7 Open Gym and Hyrox, to cater to different fitness levels. We believe that fitness should be accessible to everyone, whether you're training at our gym in Lake Zurich or enjoying the facilities at Lake Zurich Planet Fitness.

At Optimize Fitness, we don't just provide a place to work out; we provide a community where every member is supported, challenged, and inspired to reach their full potential.

Our founder, DK, knows exactly what it takes to transform your life because he's lived it. After struggling with his weight, DK embarked on a journey that changed everything.

Through dedication, proper nutrition, and consistent training, DK went from 345 lbs down to 205 lbs. This incredible 140-pound weight loss journey wasn't just about losing weight—it was about gaining a new lease on life.

His personal transformation is the driving force behind Optimize Fitness. He built this gym to provide the exact support, guidance, and community he needed when he first started his own journey.

"This is somewhat of a humbling post for me but I wanted to share some insight for those of you who struggle to stay focused and motivated. I have been in your shoes and I am still in your shoes."

"Throughout the years my weight has fluctuated a lot. I found every excuse not to exercise and made poor eating decisions. Working in law enforcement, letting my health get out of control is something there is no excuse for, as my health is responsible for keeping myself and others safe."

"In January 2024, my weight had skyrocketed to around 210 pounds and 32% body fat. Since January 2025, I have lost approximately 30 pounds of fat, dropped 15% body fat, and gained around 7 pounds of muscle."

Another incredible transformation from our community. With consistent effort, proper nutrition, and the support of our coaches, the results speak for themselves.

It's not just about losing weight; it's about building strength, confidence, and a sustainable lifestyle that lasts.
