HK Nutrition

About the Program & Coach

Hey y’all! I am Crista Lee Luna. I was born and raised in beautiful Brownsville, Texas, and I’m proud to now serve my hometown as the very first nutrition coach at HardKnox. This program has been a long time coming, and I’m honored to help launch it with care, intention, and a deep belief in the power of food to transform lives. It is an absolute privilege to bring nutrition services to my HK familia that means so much to me and I’m deeply committed to serving and uplifting the RGV community that shaped me!!!

My journey into health and wellness began in 2016, during a time when I felt completely uncomfortable and unhappy in my body. I knew something had to change. With no background in sports or fitness, I was far from living up to my fullest potential. Since then, I’ve not only transformed my own life through nutrition and movement, but I’ve also fallen in love with helping others do the same!

!I hold a Bachelor’s degree in Biomedical Sciences and am currently pursuing my Master’s to deepen that foundation. I’ve always been in awe and drawn to the science of the human body and I truly believe that food is one of the most powerful tools we have for healing, strength, and longevity! Food is medicine.

Over the years, I’ve had the privilege of working in a variety of health-focused roles that have shaped the way I approach wellness today. From serving as a medical assistant and contact tracer to speaking on public health and contributing to research, each experience has expanded my perspective. Together, they’ve strengthened my belief in the power of daily choices to influence our long-term health, energy, and overall well-being.

From 2019 to 2024, I lived in Florida, where I served as the head nutrition coach at a well-known CrossFit affiliate. I worked closely with hundreds of clients, helping guide a wide variety of journeys! Whether it was an athlete striving for peak body composition, someone working to reduce or eliminate medications through nutrition, or women preparing for motherhood by reaching a healthy, sustainable weight, I have been honored to be a part of their journey toward better health and meaningful transformations

.Now that I’m back home, I’m incredibly excited to bring everything I’ve learned to HardKnox. My goal is to help you become the healthiest, strongest, and most optimized version of yourself, fully embracing the gym’s mission through personalized guidance and support

!My approach is both science-based and deeply personal. I want each of my clients to feel confident in their body, properly fueled for their lifestyle, and empowered through knowledge of nutrition. My ultimate goal is to be a resource, a guide, and a positive impact in the lives of everyone I meet!!

If you are ready to take your health to the next level, I’d love to support you in that journey.
