Hi guys! My name is Codi Duncan and I was raised in Corona, California for most of my life. I started with baseball and soccer then moved my way into golf, and eventually into CrossFit. I’ve worked out/been competitive since I can remember. I started training around 18 years old, certified through The National Academy Of Sports Medicine (NASM), and specialize in fat loss, muscle gain, and corrective exercise. I fix imbalances if need be as well as get you to your highest level of performance. I work with clients on supplementation/nutrition, meal plans, weight management, and more. I love the fitness industry because having a client succeed is the most rewarding thing a trainer can see. Watching them accomplish something they never thought was attainable, pushing them to do their absolute best, and helping them get results is awesome!

What are your fitness goals?

I am committed to clients fitness and nutrition goals. Improve your health & live a better life.
