~Stronger Than Yesterday~

Our Story

I've always enjoyed pushing my body to its limits. From dancing ballet, to wrestling, to powerlifting, at a young age being mobile and strong was what mattered most to me. While serving in the Army in February of 2021, I sustained a life-changing injury, shattering all the bones in my right leg. Consequently, I developed compartment syndrome, and had to have about a third of the muscle in my leg amputated. After which, my medical team told me I'd never walk or run without a brace. Nor would I ever squat or deadlift again. 

I refused to accept this, so I began my journey into exercise science. I read countless anatomy books, attended schools and workshops, and took the time to attain a variety of certifications. Armed with this knowledge, I started experimenting on myself, figuring out how to rehabilitate and rebuild myself from the ground up. 

In doing so, I created a method that drew upon modern exercise science, classic powerlifting, and the golden age of bodybuilding. Through this research I created a workout style that strengthened my joints and the connective tissue alongside my muscles, allowing me to do what the best doctors said was out of reach. Today, I have almost full mobility in my leg, I’m able to squat up to 700lbs and I can deadlift near 900lbs.

Through this journey of self-rehabilitation, fitness became my passion. The complexity of the goals, journeys, and barriers that make up each individual I meet along the way has become the puzzle I most want to solve in life. And so, Firestone Fitness was born. 


This is a community created to give people the freedom to feel good in their own bodies, feel confident in themselves, and do things they never thought their minds or bodies capable of doing. Seeing the joy and success of friends and clients alike has become an unforeseen privilege, and one that I will never take for granted. Let's work together to create the best version of you, and as always, be Stronger Than Yesterday.
