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

Peptide & GLP-1
Wellness Coaching.

Training is evolving. The best coaches don't just write programs — they help clients understand every tool available for optimizing their health, recovery, and body composition.

Peptides and GLP-1s are two of the most talked-about areas in health optimization right now — and for good reason. Davis offers education-based coaching that helps you understand how these compounds work, what the research says, and how to integrate them intelligently with your training.

Whether you're already on a GLP-1 like semaglutide, tirzepatide, or retatrutide and want to preserve muscle mass, or you're curious about peptides for recovery and performance — Davis bridges the gap between your medical provider and your training program.

★★★★★

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.

★★★★★

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.

"
★★★★★

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.

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.
