ABOUT JMDII
I’m Jason Diaz Jr. —I’m a Fresno State Bulldog Alum, professional football player and the founder of JMDII Elite Performance Academy.
I created this platform because I was the athlete who wanted to do more — train harder, eat better, recover right — but I didn’t have all the knowledge or know exactly how to put all the pieces together.
Through years of trial, error, injury, and comeback…
Through training under elite strength coaches, NFL mentors, and visionary leaders…
I learned what works. And now I’ve built JMDII to hand it all over to you.
This is everything I wish someone had handed me — no fluff, no guesswork. Just everything that works at the TOP.
JMDII = Jason Michael Diaz II.
But this academy isn’t just about me. It’s about you. It’s about athletes who want more — and are ready to earn it & embody what it takes to be an elite athlete in all areas.
JMDII is built on one belief:
Discipline & Alignment Over Hype.
If you train smart, fuel your body with exactly what it needs, recover like a professional, and master your mind — your game will elevate. Period.
Every resource inside this system is battle-tested — from full workout programs, sprint protocols, nutrition breakdowns, to mindset frameworks—all created from my personal experiences in high-level training environments and the knowledge passed down to me from the legendary coaches and mentors I’ve been blessed to train under and have along my path. As my path and knowledge continue to grow and evolve, so does JMDII—this is the extension of that knowledge given straight to you.
Why JMDII?
There are a million coaches and fitness pages out there.
What makes JMDII different?
I’ve lived and continue to live all of this.
Non Starter to Starter in Highschool
All Conference
I’ve played D1 Football (on a multiple time Top #25 nationally ranked team.)
I’ve played pro.
I’ve battled injury. I’ve rebuilt.
I’ve been coached by legends and trained alongside the best.
This isn’t theory. This is the exact information that changed my body, my mind, and my performance —allowed me to do what I’ve accomplished and continue to do to this day — built into something you can follow.

Mentorship Runs Deep
My mission is simple:
To give athletes everywhere access to the blueprint I didn’t have in the beginning—that I had to forge. To build a new generation of high-performing warriors who dominate their game and their life.
Whether you buy a one-time bundle or go all in on the membership…
Welcome to the standard. Welcome to JMDII.
Founder’s Note:
I didn’t build JMDII to be a brand.
I built it because I know what it feels like to want more, to know that I am capable — and not know where to turn.
If that sounds like you then you found yourself in the right place.
I’ve been the skinny kid trying to figure it out.
I’ve been the one pushed aside and stuck on the sidelines.
I’ve been the athlete recovering from injury, asking myself if I could make it back.
Through it all, I stayed in it. I kept learning, kept testing, kept evolving & never gave up.
This platform is the result of all of it — and it’s here to serve the next generation of locked-in athletes who know they are capable of more.
If you’re ready to work…Let’s unlock what you’re capable of.
Stay sharp. Stay disciplined.
See you inside.
