I’m Dr. Holden Chance Mayfield, a physician, fitness enthusiast, and advocate for evidence-based health and wellness. My journey into medicine and fitness has always been intertwined—I’ve spent years studying human physiology, nutrition, and exercise science, not just from a clinical perspective, but also as an athlete and coach. I hold multiple degrees and certifications, including a Doctor of Osteopathic Medicine (D.O.), a Master of Healthcare Administration (MHA), a Bachelor of Science in Cellular and Molecular Biology, and a Graduate Certification in Biomedical Sciences.

--------------------------------------
As a Doctor of Osteopathic Medicine (D.O.), I’ve seen firsthand how preventable health issues like obesity, diabetes, and cardiovascular disease impact people’s lives. Too often, traditional medicine focuses on treating disease after it develops, rather than equipping people with the tools to prevent it in the first place. I wanted to change that.
--------------------------------------
That’s why I founded D.O. Better Fitness—a brand built on the belief that science-backed training, proper nutrition, and medical insight can help people optimize their health for the long run. Unlike trendy fitness programs that focus on quick results, my goal is to build a sustainable, supportive community where people can truly understand how their bodies work and why certain training and nutrition strategies are effective.
--------------------------------------
I bring my background in medicine, healthcare administration, and fitness to bridge the gap between the gym and the clinic—because real health isn’t just about aesthetics; it’s about longevity, functionality, and overall well-being. Whether through educational content, personalized coaching, or community-building, my mission with D.O. Better Fitness is to empower people with knowledge and tools they can apply for life.
--------------------------------------
Through this platform, my foremost goal is to educate—to provide a place where anyone can learn the fundamentals of fitness, health, and wellness. Whether it’s through our educational YouTube channel, guided training programs, evidence-based nutrition advice, or teaching how to work out effectively and appropriately, D.O. Better Fitness is built on the principle that knowledge is power.
--------------------------------------
Beyond just physical fitness, we emphasize the value of the mind, body, and spirit, helping individuals create a balanced, sustainable approach to lifelong health. I want this to be a community where we can all learn, grow, and push each other to do better together. Because when you combine medical expertise with fitness science, you don’t just get results—you build a healthier, stronger future.
Let’s D.O. Better, together."
At D.O. Better Fitness, I’m not just here to tell you what to do—I’m here to empower you with the knowledge and tools you need to take charge of your health for life. Too often, fitness trends push quick fixes and unsustainable results. But real health isn’t about crash diets or endless cardio—it’s about understanding how your body works and applying science-backed strategies that actually make a difference.
