Meet The Team
Gracie Rodney
Gracie Rodney, a NASM Certified Personal Trainer and Group Instructor whose passion for fitness began with my own transformation journey. After experiencing firsthand the power of proper training, I committed myself to helping others achieve their fitness goals through both personalized training and dynamic group classes.
My commitment to understanding the human body drives my continuous education. Beyond my advanced training through the Brookbush Institute, I'm currently pursuing massage therapy certification to deepen my knowledge and better serve my clients. I combine this growing expertise with genuine enthusiasm in every session, providing both expert instruction and motivational support—complete with energizing playlists! Nothing is more rewarding than helping my clients discover their strength and achieve their fitness goals.
Agnes Prehn
Originally from Holland, Agnes Prehn moved to Hawaii in 1986 and has been in Kailua-Kona ever since. Prehn worked in the health and wellness industry for over 30+ years. After a health scare in 2016, Prehn decided to take control of her own health. In 2019, after 22 years, Prehn separated from her job as the sales director for Nutrex-Hawaii, the makers of BioAstin, to pursue her passion to help the community by providing fitness and nutrition guidance.
After her separation from Nutrex, Prehn completed certification from the American Council of Exercise (ACE) and Precision Nutrition (PN) to become a group fitness trainer and a fitness nutrition coach and started her own fitness classes via BurnFitness808 to make a greater impact on improving health and wellness in our community.
"Agnes can change your attitude in one session..."
Agnes is the best. She has changed my perspective on the fitness world. Not only does she kick your butt, it’s incredibly fun. Agnes can change your attitude in one session and flip your mood wanting more. I have been working out with Agnes for over a year and I’ve never been happier. Not only with my appearance but my mental health and the way I have a relationship to being healthy.

"Gracie kicks your butt"
Gracie's workouts always kick your butt. They are always different, dynamic and super fun. They leave you dying at the end of the day, but excited to come back! Not to mention her stretch and release classes are the best I've ever been to for relaxing your muscles, after you've grunted in pain more than a few times!
