Not sure what’s limiting your performance?
The Athlete Performance Assessment gives you an opportunity to tell me what’s going on: your goals, your training, what’s frustrating you, and what you feel may be holding you back.
I’ll personally review what you share and recommend what I believe is the most appropriate next step.
There’s no obligation to purchase anything, and no commitment required. You’re simply sharing enough information for me to better understand the problem and point you in the right direction.
Sometimes the first step toward performing better is simply figuring out what needs your attention.

HYROX Nashville is coming. You still have time to change what happens on race day.
I’ve opened a limited number of assessment dates at Diaz Human Performance in Franklin for Nashville competitors. We’ll identify how you move, how your physiology responds to intensity—and then take what we learn outside and verify it at pace.
You have time. But none to waste. Details at the link in bio.

Your performance limit isn’t simply a matter of fitness. As pace and stress increase, breathing changes, tension rises, movement begins to deteriorate, and eventually the nervous system tells you to back off. The goal isn’t to blindly fight that response—it’s to recognize it, control it, and gradually move the barrier. Breath rhythm can become an incredibly powerful part of that process. Start controlled. Experiment with the relationship between your breathing and your steps. Notice what happens as pace increases. There is no magic breathing ratio that fits every athlete—the objective is to discover the rhythm that allows you to remain composed, mechanically sound, and productive under pressure. Better breath. Better movement. Better decisions. Better performance.

Some people bought RUN. before they knew what it would become.
You took a chance on the work early. I remember that.
Since then, RUN. has become something more — including The RUN. Experience audiobook: 18 chapters and more than 9 hours of audio.
So I want my early RUN. adopters to have it on me.
If you were one of the people who purchased RUN. early, send me a DM with RUN VIP. I’ll verify your purchase and send you a private code to get the audiobook free.
No public coupon code. No catch.
Just a thank-you to the people who supported the work from the beginning.
You were there first. I haven’t forgotten.

Working harder isn’t always the answer.
When progress stalls, the problem may not be effort. It may be running mechanics, physiology, training decisions—or something you’ve never actually measured.
That’s what I do.
I identify what’s costing you performance, show you what it looks like, and help you decide what to do about it.
Not sure where to start?
Take my Athlete Performance Assessment. It takes just a few minutes and gives me enough information to point you in the right direction.
