Achieving your fitness goals with a full life and busy schedule can be overwhelming. And, when it comes to nutrition and how to properly use it to help you achieve your goals, there's a lot of misinformation out there that can make sticking to a plan impossible (or, at least not enjoyable.)


But we know it's possible - and quite honestly a lot more simple than you may think.

This is our "WHY" behind IronBox Nutrition.

Our mission is to change the way people view fitness and nutrition, help them break through mental and physical barriers holding them back, and become the best version of themselves.

Will it be "easy"? Not at all. You might have to break some hardwired beliefs about what you think it takes to achieve your goals. PRFM Nutrition is here to help take the guesswork out of your nutrition AND provide you with the tools and education to make this a lifestyle you can stick with for years to come. 

Our biggest motivation is you, your goals, and helping you achieve them without restriction.


IronBox Nutrition is founded by Mary Terrell. With over a decade as a Personal Trainer and Crossfit and Nutrition Coach, combined with personal experience in discovering how to achieve her own goals without sacrifice, she's helped hundreds of people live healthier, happier, stronger lives while loving the process.


Like many, Mary's fitness journey has been full of ups and downs. She struggled for years to find balance between nutrition and fitness - convinced having the results she wanted meant making a ton of sacrifices in the process.

May spent years stuck on the yo-yo dieting hamster wheel, restricting the foods she loved because that's what she thought she had to do.

It wasn't until she learned the magic of properly fueling her body that she began seeing the results she wanted all along. Without restriction.

Mary's journey led her to graduating with a Bachelor's degree in Nutrition Science from Auburn University, becoming a certified Personal Trainer, CrossFit Coach, and a WAG certified Nutrition Coach.

Today she helps people all over the world feel the best they ever have and achieve the results they want without the sacrifices they don't.

At PRFM, we understand your life, nutrition background, and goals are unique. You are not a cookie cutter person and neither should be your approach to nutrition.
