About Davis
aka "Coach Diesel"

I'm More Than
Your Trainer.

I'm an Austin native and strength coach with over a decade of experience. My background spans Olympic weightlifting, CrossFit, private personal training, and life coaching — because I believe physical training and mental development are inseparable.

What fuels me most is working with people who are willing to improve their own lives. Coaching, for me, is about supporting that commitment and helping it translate into real, lasting change.

I also believe coaching isn't a universal model. If we meet and it's not the right fit, I'm happy to connect you with someone better suited for you. That's how much I care about your progress.

The New Era of Training

Your Clinic Prescribes.
We Make It Permanent.

Your doctor prescribed the medication. Your clinic manages the protocol. But who's holding you accountable on Tuesday when you skipped the gym? Who notices your sleep is off and adjusts your training? Who catches the pattern before it becomes a plateau?

That's the gap. And it's exactly why most GLP-1 results don't last. Clinics don't have the capacity to check in with you daily — that's not their job. Accountability, structure, and lifestyle integration is the coach's job. Without it, the medication has no foundation to build on.

Davis's clients don't just lose weight on GLP-1s. They achieve body recomposition — losing fat while building or maintaining muscle simultaneously. That's considered nearly impossible in a caloric deficit. His clients do it consistently. The difference is the training program is built specifically around the protocol, not despite it.

Whether you're on semaglutide, tirzepatide, or retatrutide — Davis bridges the gap between what your clinic prescribes and the results that actually last.

Recomposition

Lose fat. Build muscle. Simultaneously. Davis's clients consistently achieve body recomposition on GLP-1 protocols — considered nearly impossible without the right training methodology.

Daily Accountability

Your clinic can't check in with you every day. Davis can. Accountability between appointments is what separates people who get results from people who plateau.

Built for Permanency

The medication creates the window. The training and habits Davis builds with you make the results last — long after the protocol ends.

Metabolism Acceleration

GLP-1s can slow your metabolism through muscle loss. Strategic resistance training reverses this — building a faster, stronger metabolic engine while you lose fat.

What GLP-1 Coaching With Davis Actually Looks Like
The Missing
Piece.
  • Daily accountability between clinic appointments
  • Training built specifically around your injection schedule
  • Muscle preservation — so you lose fat, not lean mass
  • Body recomposition: fat loss + muscle gain simultaneously
  • Metabolism acceleration through strategic resistance training
  • Habit and lifestyle structure that outlasts the medication
  • Nutrition and electrolyte guidance on protocol
  • Real check-ins — not a portal, not an app. A real coach.

Coach Davis is one of the best in the business! His knowledge, energy, and motivation helped me reach goals I never thought were possible. Everything from talks about life during warm-ups to pushing me to finish strong — 5 stars, truly a blessing.

Logan C.
Private Training Client
"

I gained 10lbs while getting my body fat under 10% — all from Davis's diet tips and programming. He helped me dial in nutrition AND perfect my lifts. He is by far the best motivator I know.

Parker S.
Strength & Nutrition
"

In one year: 175lb deadlift, 85lb push press, cut 16 minutes off my marathon time, and I'm noticeably leaner. Davis tailors every workout around my running schedule. Working with him is genuinely FUN.

Strength & Endurance

Davis helped me shore up my weak muscles, and I noticed my resting heart rate going down over time. Feeling stronger, more functional, and with way more endurance. The man knows his stuff.

Davis guided me through shedding 20lbs and gaining significant strength — but also offered invaluable support in life beyond the gym. He's not just a trainer. He's a mentor who invests in your holistic wellness.

Got Questions?

Frequently
Asked.

Absolutely not. I work with beginners and experienced lifters alike. Every program is built around your current level, movement history, and goals. We start exactly where you are.

Most clients train two to three times per week, while sport-specific or performance-driven programs may involve more. Programming is always tailored to your schedule, goals, and recovery capacity.

People from all walks of life who are ready to take ownership of their wellbeing. Background and experience don't matter. What unites my clients is a willingness to show up and put in the work. The goal is progress, not perfection.

That's what the initial call is for. Coaching works best when there's genuine alignment. If it's not the right fit, I'll happily recommend another coach who may be better suited for you. My goal is your success — period.

I train at select strength facilities across Austin, and also offer in-home or residential gym sessions. Location is flexible and determined by what best supports you and your training goals.

Simple — schedule a call and we'll take it from there. No pressure, no hard sell. Just a real conversation about where you are and where you want to go.
