My Current Slate of Fitness Mentors
Learning from the best
Before we start:
-Elite Research is who I recommend for peptide research. Use code AJAC10 at checkout
-If you a founder, operator, business owner, get yourself a Chief Health Officer to stay strong and fit while your building your business. Talk to Velocity health.
We are always in the act of creating ourselves
From 2010 up until the end of 2026, my professional life was health, exercise, fitness. I was a full time personal trainer from 2010-2017, and then committed to being a creator from 2017 onward.
Over the course of those years, I had a recurring struggle, not with burnout, but rather BOREDOM.
Health and fitness can get repetitive. Same questions, same conversations, same arguments, same subjects that you are endlessly repeating yourself on.
While the field of health science has progressed, the fundamentals have never changed. This is good in that we know what works quite clearly, but it would get stale as a subject.
Im an innately curious person and always want to be learning new things, thus every year Id have periods of not studying or paying attention to anything to do with fitness for months on end, and would instead go into various rabbit holes of research.
In the middle of the year, it was deciding to get into supplements.
I formulated Neurovolt for brain metabolism and delivering cognitive energy memory and focus, and in the frustrating process of trying to get it to market, I learned how much the USA lacks real manufacturing ability for Nutraceuticals. Sourcing quality ingredients was a primary concern
Neurovolt DID finally get made, 3rd party tested, and its now for Sale
In the frustration of that experience came to learning that Creatine monohydrate is is about 90% made China, 10% made in Germany.
Why cant we make Creatine in the USA?
Because beyond the Creatine itself, there is a massively bigger supply chain that America lacks, and we are missing key capabilities in Defense, Manufacturing, Pharmaceutical production.
Come December of last year, I brain dumped on X, to surprisingly enthusiastic response.
Then I recruited a team of scientists and engineers. Then we started working to get the supply chain back. Then I attended a Hard Tech Accelerator.
Now we have some enormous announcements coming. We have investors. Development is happening, so is building.
There has been some level of incredulity from people,
AJAC, are you REALLY going all in on this industrial project? You have a REAL company that will be making creatine and specialty chemicals and building factories?
YES.
That ironically brings us back to fitness.
My daily life has changed dramatically, I am in calls and meeting and steering the proverbial ship. There is a team of 20 people I lead (yes really).
Along with communicating, my time is spent researching chemistry, engineering, supply chains, and industrial manufacturing.
My free time is limited.
When I do need a break, I exercise…and I listen to Fitness content
Fitness has become the thing that gives my mind a break, because its FAMILIAR
What I listen to is high level and more for advanced lifters and coaches, its not '“causal” listening for someone who is a noob.
That said, I wanted to share my favorite creators with all of you, and what Ive learend from them
Jonathan Warren-The Expansion/Compression Model
Jonathan is a veteran personal trainer in Orange Country, California. Him and I are similiar in age, and he’s been training clients for close to two decaces.
Jonathan is a student of Bill Hartman, a physical therapist who has pioneered a dynamic anatomical model of the human skeleton not being fixed and static like a terminator skeleton, but rather are able to compress and expand in structure in alignment with breathing and loading and movement.
Simplified, your rib cage and pelvis are able to expand and compress
=ECM, Expansion Compression Model
As Warren is a competitive bodybuilder, he uses this model in training, and illustrates how lifting weights is not simply moving something from Point A to Point B. On a deeper level, its understanding how your muscles and skeleton are dynamically moving in real time.
The obsession with Range of Motion is a misplaced focus on the weight, and it tends to ignore whats happening with the joints and muscles themselves.
Id suggest starting with his ECM video
And then seeing what others interest you. His videos on troubleshooting training are phenomenal
Eric Seifert-Muscle Activation applied to real life training
Eric is AMAZING. He has the best hands on instruction of movement form, mechanics, and deep understanding of anatomy and physics that Ive ever encountered.
His background is combination of being a neuromuscular therapist trained Muscle Activation Technique, and then a strength coach.
His videos are often him training real clients, and its magical how he can solve problems most lifters struggle with for years.
Every video breaks down muscle activation, movement assessment, and how equipment mechanics all work together.
He constantly makes the point that most injuries, stalled development, and chronic joint pain don’t come from a lack of effort, they come from poor fit, poor execution, and misunderstanding how the body interacts with machines and lifting implements, be that a barbell, a dumbbell, leg press, or something else.
Eric is the best example of truly PERSONAL training.
He doesnt have templates and copy paste workouts. He doesnt guess.
Every session is real time assessment, real customization, and real results.
If you’ve ever struggled with “I train hard but this muscle won’t grow,” or “this exercise always hurts,” WATCH his videos.
