behind the coaching
A four-year degree in nutrition science: metabolism, macronutrient physiology, how food actually moves through the body. It's the floor, not the ceiling. What separates real coaching from a textbook is applying it to the person in front of you, adjusting for how they're actually responding instead of how a study average says they should.
The industry-standard certification in exercise science, program design, and injury-aware training progressions. It's useful shared vocabulary for coaching people through resistance training safely, not a substitute for the thousands of hours actually spent coaching lifts in a room with real people.
A coaching certification focused less on macros and more on behavior change: getting someone to actually follow a plan long enough for it to work. Most nutrition failures aren't a knowledge problem, they're a consistency problem, and that's what this trains a coach to address directly.
Head coach of group classes at Vickery Athletics since 2021, running sessions anywhere from three to fifty people at a time. That volume of real coaching hours, watching how different bodies respond to the same movement, is where the actual education happened.
the approach
decision-based coaching
What sets this apart is the philosophy, not the certifications. Call it the love child of old-school high-intensity training and modern science-based lifting: optimize resistance profiles over stability drills, train to real failure over plyometrics, control range of motion to isolate the muscle doing the work instead of chasing novelty like battle ropes.
Most coaches lean on outdated, one-size-fits-all models. Coaching here is built around decision-making, not templates: training, nutrition, recovery, exercise selection, and workload adjusted every week based on how you're actually progressing, not how a spreadsheet predicted you would.
education + teaching
as a coach
I've taught classes at Vickery Athletics in the heart of Dallas, Texas since 2021, with two of those years also teaching classes at Recess Fitness Club.
I have a degree in nutrition, a NASM certification, and a Precision Nutrition Level 1 certification. Those are the floor, not the ceiling. What actually shaped how I coach is everything since: training in various gyms, coaching classes ranging from three to fifty people, self-prescribed experiments, and years of deep research layered on top of the fundamentals.
Today, I help my clients break down their limitations and push hard to be the best version of themselves. This works best for people ready to train hard, eat with real intention, and trust a plan that adjusts to them instead of a spreadsheet, whether you're a beginner or already deep into training. If that's you, I can help you reach your goals sustainably and unlock your true, deep health and potential.

worth asking
Who is Stefan Rueda and what makes his coaching different?
I'm a student of life. Born in Mexico. Raised in Dallas since I was five. I lived a year in Paris at eighteen. I'm trilingual. Most days you'll find me coaching clients somewhere between an espresso and my own training session.
What sets me apart is the philosophy. Call it the love child of old-school high-intensity training and modern science-based lifting. Certifications matter, but they're trivial next to the approach: optimize resistance profiles over stability drills, train to real failure over plyometrics, control range of motion to isolate the muscle doing the work instead of chasing novelty like battle ropes.
Most coaches lean on outdated, one-size-fits-all models. My programming is built on what actually matters: progressive overload, movement optimized for hypertrophy, nutrition coaching with real accountability, and a coach who will call you out on your bullshit.
Do you coach online, or only in person in Dallas?
Both. The coaching on this site, nutrition and personal training, is fully online. Programmed and updated weekly, no matter where you live.
I also coach one-on-one in person in Dallas (Uptown, Lower Greenville, Knox-Henderson, Downtown, Old East Dallas), and I've been head coach of group classes at Vickery Athletics since 2021.
Who is this coaching not a good fit for?
I can coach anyone willing to commit real time and energy to their health and trust the process. What doesn't work: someone chasing a generic template, a quick fix, or a coach who won't call them out.
This is driven equal parts from data and discipline. Weekly check-ins. Honest food tracking. Adjustments based on how you're actually responding, not how a spreadsheet predicted. If you won't be consistent and honest with me, it won't work.
Why do you limit the amount of spots available?
Keeping the number small is intentional. Spread across too many clients and the coaching turns generic. A limited roster is what lets me give every client the depth of attention their program actually needs.
What results can I realistically expect, and in what timeframe?
Depends what we're working on. Training and programming: quick neuromuscular adaptations first, then slow, steady gains in strength and muscle mass.
Nutrition coaching: reclaiming your health as a whole. Better digestion. 5 to 10% body-fat reduction. Clearer mental focus. A fixed sleep cycle.
Some clients see change in 4 weeks, clear change by 8, noticeable and tangible change by 12. Complex issues can take 8 months or more. It comes down to complexity and commitment.
