Meet Crystal Duke - Your Health and Fitness Coach

Coach Crystal never planned on becoming a fitness and health coach. Her journey began while working as a speech-language pathologist, where she cared for adults facing serious health conditions. Over time, she noticed the same underlying issues—high blood pressure, diabetes, high cholesterol, obesity—often rooted in years of unmanaged habits.

But the turning point came at home.

Crystal’s mom had always been hesitant to change her lifestyle. One day, Crystal joined her at the gym and saw how unsure and uncomfortable she felt. That moment sparked a decision: they would take the journey together. With small, steady changes, her mom gained confidence, energy, and a transformed sense of self.

And Crystal gained a deeper understanding of what so many women truly need—support, education, and someone to walk alongside them.

From that experience, CLifeFit was created.

Today, Coach Crystal works with women to build sustainable health habits and real lifestyle change. She collaborates closely with her brother, Dr. Doran Duke, an internal medicine and obesity medicine specialist at ARCD Weight Loss Management in Marietta. Together, they use advanced diagnostics to create accurate, personalized weight-loss plans that focus on long-term success.

Crystal’s mission is simple:
help women gain confidence, understand their bodies, and finally feel empowered on their health journey—one step at a time.
