"His legs are shorter. Her Torso is longer. He taped his ankles playing basketball in college. She had rotator cuff repair and a c-section. His elbows cannot lock out. Her hips are dysplastic. 


So what does this mean?


Without the personalized approach, let's look at a scenario many other gyms take with the example of Squats. From the examples above, one should do step-ups instead of squatsanother should do box squats, and another would benefit more from lunges instead of squats.


This isn't modifying, or scaling. These aren't lesser movements, with the back squat being the king.


This is individualizing. This is understanding you so well, we can provide you with what YOU NEED! 

You shouldn't be forced into a "one size fits all" approach. 

Honestly, we used to do this too. We didn't know then what we know now. 

But we observed, learned, and changed to better at what we do to help people just like YOU!


Our mission is to build better humans through the EDUCATION of HEALTH & MOVEMENT!

We'll help you learn what you need, to feel the best you ever have. WE ARE DIFFERENT! We are professionals. We are the healthcare providers of the future!


We want to meet you! Schedule a stress-free 1-on-1 intro. We want to take the opportunity to get to know you and your goals.  You will feel seen and heard.  Based off of your joint by joint assessment, we will design a program, just for you, to help you reach those goals.  Your coach with walk with you, step by step, on your journey.  Are you ready?


we are and why we care

We [Cheri and Andrea] founded Element 26 Fitness, LLC home of FeRRUM Athletic Company, in 2012.


Our primary purpose was to bring functional fitness into the Julington Creek area of Jacksonville.  With no other type of fitness facility in the area, our original thoughts were that nobody would show up.  Nine months after opening, we were in need of our first expansion.

Through the years, we have experienced both personal and professional growth. We have recently built a new, studio style gym in the heart of Mandarin. This new location is built on premier personal experience for the coach/client journey.

Our focus is on the continual education of ourselves and our staff, for the betterment of YOU, our clientele.  The vision is to build better humans by educating, empowering, and enriching the coach while they guide, value, and educate the client, leading to improved longevity for all. 


When caring for others is the top priority, a fitness professional never spends a day working in their entire life.


"I’ve had two back surgeries and was told by my neurosurgeon in 2012 that I could never lift anything over 30 lbs again. When I walked in to the FeRRUM gym and met Cheri, I was 46 years old, my knee was the size of a large grapefruit due to a current meniscus tear and arthritis, and I was also dealing with having a lumbar sprain. My goals were small and I just wanted some relief and small gains in strength and movement. Seven months later my body is completely changed. I can lift more weight than I was able to in high school (I was an active bodybuilder from my late teens to my early twenties), I have stamina like I’ve never had in my whole life, and I feel better than I have in a decade. Cheri and FeRRUM have changed my life. I never thought I’d be able to feel this way in my late forties."

"When I joined a year ago (heck, even 6 months ago), I couldn't lift anything from the floor with my limited mobility. Deadlifts meant I'd be working from my bed on a heating pad for the next couple of days. I kept at it though, took advantage of the conditioning and coaching from your amazing staff. I improved my form dramatically and and I'm stronger now at 42 than I've ever been in my life. My goal when I started was to be able to do yard work without hurting myself. Look at me now! I can't wait to see where my second year at FeRRUM takes me! My goal when I started was to be able to do yard work without hurting myself. Look at me now!

"If someone had told me “You’d benefit greatly from a functional fitness workout”, I would have laughed. Here I am, having worked with Sean and Cheri for ten months! I’m toned and stronger than I’ve ever been, despite being 61 years old. Sean got me started at a pace I was comfortable with; he gave me faith in myself. Cheri has driven me to complete workouts specifically designed for functional fitness that work muscles I didn’t know I had. She really listens to my feedback as to what feels uncomfortable, diagnoses what the root cause is and gives me movements to work through it and become stronger. Weight loss is not a key to better health, strength is. I’ve lost only 5 pounds, but wear a size smaller than when I started this journey. I feel great – physically and mentally. I actually said “I don’t mind coming here” the other day when I came to the gym! Never thought I’d speak those words about a workout."

We will answer all of your questions, make sure you are heard, and make a plan to move forward. From there, our assessment is a joint by joint break down of how your body is currently moving.  This is our starting point for building our program, just for you.




Our elements program is the start of your individualized journey.  This is 1:1 personal training, 100% designed with what you need, where you need to start, and progressing you at your speed.  Meeting you where you are is an important step to helping you reach your goals successfully.  This program involves corrective exercises, lifestyle discussions, mentorship, strength building, and helping to build your confidence and competence to move you up the mountain toward your goals.
