Welcome to Crucible CrossFit, where community, fitness, and personal growth come together.

Established in 2009, Crucible has been a cornerstone of the Jacksonville fitness scene for over a decade. In 2012, Colleen Lehane took over management and programming, officially purchasing the gym in September 2013. Under her leadership, Crucible has flourished, growing to over 150 members and serving a diverse community of athletes—from beginners to CrossFit Games competitors.

At Crucible, we believe in building a strong foundation in fitness. Our approach is rooted in the core principles of CrossFit: mastering basic mechanics, emphasizing consistency, and developing intensity at every level. Whether you’re stepping into the gym for the first time or pushing toward elite performance, our dedicated coaching staff is here to guide you every step of the way.
Our team is comprised of highly qualified coaches with degrees in Exercise Science and years of experience in the health and fitness industry. We take pride in offering personalized support, including movement modifications for beginners and injured athletes, as well as advanced training for those looking to enhance their strength, conditioning, power, and speed. Whether your goals include competitive CrossFit, sports performance, OCR, running, or endurance-focused racing, we have the expertise to help you succeed.

Beyond CrossFit, we offer a variety of fitness programs tailored to meet diverse needs, including yoga, conditioning, Pr4m (a non-barbell CrossFit option), CrossFit Kids and Teens, Hyrox, and Nutrition Coaching. Our mission is to provide a welcoming space for all, no matter the time of day, where you can learn, grow, and thrive in health, wellness, and fitness.
