Who we work with
Built for serious people who get things done.
We train professionals, clients over 50, post-therapy returns, grandparents, young athletes, and everyone in between. Programming is individualized, and always will be.
Training after 50
Programming built around joint health, mobility, and sustainable strength — not trend workouts. Measurable progress you can feel in daily life, month over month.
Returning from injury
Work alongside your PT or surgeon. Every session logged so your medical team can see exactly what you're doing and how your body is responding.
Athletic performance
Strength, power, and conditioning programming for recreational and competitive athletes. Periodized around your season and your sport, not a generic template.
How it works
See open slots →Booked in 60 seconds. Billed weekly, on your schedule.
01
Pick a time with a specific coach
Browse open slots on each trainer's real calendar. You see who you're training with and the exact times they're available this week — meet the coaches and their specialties right on this page.
02
Weekly billing — no annual contracts
Billed every Sunday for the week ahead. Pause, change plans, or cancel from your dashboard — training continues through the end of the week you've already paid for.
03
Show up and progress
Your coach walks in prepared. Every lift, set, and session is logged to your dashboard so you can see strength, body composition, and adherence over time.
Why private, not a gym
You get a coach, not a gym membership.
The difference between "training" and "exercising" is measurable: someone who knows your body, programs against a specific goal, and shows you progress in numbers over time.
One coach, every session
You see the same credentialed coach every visit. They know your history, constraints, and goals — the opposite of a floor trainer rotating between clients and hoping to remember names.
Programming built around you
Each week's workouts are written against your current baseline and objectives. No templates, no 'workout of the day' that ignores your knee, your schedule, or last week's progress.
Every session measured
Lifts, sets, body composition, adherence — logged to your dashboard and reviewed before your next session. Progress is visible, not anecdotal.
Nutrition built in
A personalized plan with recipes and grocery lists — not a supplement upsell. Updated as your body composition and goals shift.
Why clients stay
Five reasons our clients keep coming back.
Ask any of them and these are the answers you hear. Not the marketing pitch — the actual reasons training here earns a standing slot on a busy week.
Thirty minutes. In, worked, out.
Your trainer has the equipment racked and the session scripted before you arrive. Every movement is calibrated to where your body is that day — no warm-up confusion, no wasted reps. Train well and get on with your day.
Progress you can see.
Every rep, load, and lift is logged to a digital record that charts your history and surfaces trends. Training becomes something measured — not something you hope is working.
Nutrition tuned to your life.
A plan built around how you actually eat, travel, and entertain — not a template. Monthly body-composition readings keep the plan honest, so adjustments come from data rather than guesswork.
Method refined over two decades.
Simple, proven, science-led programming — the product of twenty-plus years and thousands of clients. We don't chase fitness trends; we use what consistently produces results.
Coaching, not combat.
No yelling, no grinding, no ego. Every session is scaled to what your body can handle today — intelligent, sensible training that builds strength without breaking you down.
Your coaches
Credentialed coaches, not floor trainers.
Every coach on our team is nationally certified with real specializations. You pick the one whose background matches your goals when you book.

David is the best personal trainer for results and sustainability! The 30 minute session times are the perfect length to be able to crank out a good workout but also not spend hours in the gym after a long day at work. David makes the work outs fun while also making sure you are making progress towards your goals. I could not recommend DNA personal training and David more highly. 10/10.

David is everything someone would want in a trainer. Your strength conditioning program will be completely personalized to you and you are working in his private gym where it is just you and him for the time that you are there. He is compassionate, wise, assists with nutritional needs, and memorizes your injuries and sore spots so that he can customize the workout around them. He has assisted me greatly with the mental challenges of working out, using both humor and teaching. I have truly looked forward to my workouts as a result!

David is the best trainer ever!!! In 30 minutes you will receive a workout that is a perfect combination of strength exercises and cardio. David is also a great trainer for ALL ages. I’m in my 50’s and started to have some mobility issues with my knees and ankles. In a few short months I have noticed huge improvements. If there is something that is difficult, he always has a modification. I love DNA personal training and I know you will too! Don’t forget to ask him about nutrition(which is included in your membership),if you follow his program, you will drop weight quickly!

I started my training with David almost a year ago, and it has been a life changing experience. When I began my training, I was recovering from a severe shoulder injury. I could not lift my arm above my waist without extreme pain. With David's expertise and strategic conditioning, my shoulder is better than ever and I am now able to focus on long term fitness and wellness goals. David is knowledgeable, patient and provides a judgement free atmosphere where everyone can feel comfortable about their current fitness level and where they want to go from there.

I trained with David a long time ago, back when he was still located downtown, so this review is long overdue! But David is a phenomenal trainer who helped me to get on a path of taking better care of myself. I started out with no experience or confidence in my ability to do anything in the gym, and left (moved out of AZ) able to continue the plan he had worked out. Thank you David!

Where we train
Tucson, with Marana coming soon.
Train where it fits your week. Same programming approach, same standards at each location.
Frequently asked
Questions, answered.
What makes your approach different from a typical gym trainer?
Every session is private one-on-one with a credentialed coach who programs each week against your specific goals — no generic workout templates, no trainers splitting attention across multiple clients on the floor. You get the same coach every session, so they know your history, your constraints, and what's working. Sessions are 30 focused minutes — designed to deliver results, not fill time.
Who are the coaches and what are their credentials?
Our coaches are credentialed professionals holding current nationally-recognized certifications, with backgrounds ranging from post-rehabilitation and strength-and-conditioning to athletic performance and training clients over 50. When you book, you choose the time and coach that fit your week — and every coach's bio is on this page under Coaches.
How is progress measured and tracked?
Every lift, every set, every session is logged in your client dashboard — not a paper notebook. You see trends over weeks and months: strength gains, body composition changes, personal records. Your coach reviews this before every session and adjusts programming accordingly. Measurable progress is built into how we work.
How does training fit into a busy professional schedule?
Sessions are 30 minutes by design — short enough to fit a lunch break or a window before work without turning your day upside down. Because everything is logged in your dashboard, your coach walks in knowing exactly where you are; no time wasted recapping or writing things down mid-session.
What's included in a membership?
Each membership includes private one-on-one coaching with a credentialed trainer, a personalized nutrition plan with recipes and grocery lists, body composition and lift-history tracking, and full access to your client dashboard. No add-on fees and no upsells.
What does it cost and how does billing work?
Memberships are weekly, billed every Sunday for the week ahead: $89/week for two sessions (Tue/Thu) or $126/week for three sessions (Mon/Wed/Fri). No long-term contracts — cancel anytime from your dashboard and training continues through the end of the week you've already paid for.
