I'm Tyler Greer — a Master CHEK Practitioner and root-cause health coach with 20+ years of clinical experience. I investigate the drivers of chronic pain, fatigue, and dysfunction that conventional training, physio, and medicine consistently miss — then build you a fully personalized plan to fix them.
You wake up already running on empty. Coffee barely makes a dent and energy crashes derail your afternoons.
Aches and tension that move around, don't respond to treatment, or keep returning despite your best efforts.
Struggling to focus, forgetting things, feeling mentally slow — not the sharp professional you used to be.
Programs work briefly then you're back to square one. You need a sustainable approach, not another plan.
Doctors say nothing is wrong. But you know something is off — and you're not making it up.
Your career demands peak performance. Your body's running on fumes. The gap keeps widening.
I started where most people in this industry start — as a personal trainer. What pulled me toward deeper work was watching the fitness world chase aesthetics while people kept getting sicker. The CHEK Institute system reframed everything: holistic health, integrated systems, the right way to actually build a healthy human instead of just leaning one out.
It got personal. I grew up overweight with bad acne and a diet of sugar and processed food. The shift started with one moment in high school — water-concentrated fruit during football hell week, and the way I felt afterward. That cracked open everything. I dropped 55 pounds that summer, gained 20+ pounds of muscle the next year, and thought I'd figured it out.
I hadn't. The transformation looked good on the outside, but I was still living on poor habits — and it caught up with me. Digestive issues, mercury toxicity, fungal overgrowth: problems conventional fitness has no answer for. CHEK and FDN became the frameworks that pulled me out, and they're the same frameworks I use with every client now. Paul Chek's work is the lens; FDN labs are how we see what's actually happening underneath.
Today I work with clients at my private studio in Renton, WA and via FaceTime or Zoom worldwide. My favorite people to work with are the ones who genuinely want to be healthier — not just look better. Looking good is a side effect of doing the deep work. Married to my wife Katie, raising our son Kingston, training in our studio in Renton — I live what I teach, with the same human imperfections everyone has. Always learning, always progressing. I expect the same from the people I work with.
Five service areas, all driven by the same root-cause method. Available in person in Renton, WA — and online worldwide for clients who need clinical depth, not just a workout plan.
Flagship · 1:1 Ongoing
The full functional health practice — investigation, programming, and ongoing coaching combined into one ongoing relationship. Built for chronic, layered issues that haven't responded to fitness, diets, or symptom-only protocols.
Functional Lab Testing
For fatigue, hormone imbalances, gut dysfunction, brain fog, HPA-axis burnout, and the "I know something is off but nothing's working" feeling. Focused investigation of the systems conventional care keeps missing.
Lifestyle & Stress Coaching
The CHEK "4 Doctors" framework — Dr. Quiet (stress & sleep), Dr. Diet, Dr. Movement, Dr. Happiness — applied to your whole life as one integrated system. Lifestyle redesign that actually sticks.
Online · Worldwide
Custom corrective programming for chronic pain, postural dysfunction, and movement compensations — delivered online with video, written programs, and weekly form feedback. CHEK Practitioner approach, not generic exercise libraries.
Online · Worldwide
Full-program online coaching for clients who can't train with me in person but want the same depth. Movement, nutrition, recovery, and lifestyle — all integrated into one program with direct access between sessions.
First Step · Free
Not sure where to start? Take the free 24-question root-cause self-assessment to see what's likely driving your symptoms — then decide if you want to schedule a discovery call or book the full Root Cause Assessment.
Six steps from your first conversation to your three-month reassessment — every step grounded in actual data, not guesswork. The same CHEK + FDN process I've used with clients for 20+ years.
A free 20-minute conversation. Your story, your goals, what you've already tried — and an honest answer on whether I'm the right fit before you commit a dollar.
The full intake. In-person (Renton) covers movement, posture, and pain in a 2-hour session. Online uses the same CHEK assessment battery delivered via PTEnhance — completed before our first working session.
I review every assessment, score, and pattern — then build your specific plan. Movement, nutrition, recovery, and lifestyle priorities mapped to your 4 Doctors profile.
This is where the work happens — sessions (in-person or online), program execution, real-time adjustments, and direct access between sessions for the questions that always come up.
Between sessions, you complete short CHEK assessments to track stress, sleep, nutrition, energy, and recovery. I see the trendline — not just how you feel today — so we can adjust before plateaus hit.
Full re-evaluation of the assessment battery. We compare scores, posture, movement, and the 4 Doctors graph against your baseline — then evolve the program based on what actually moved.
5-star Google reviews from clients training with Ty — from a few months in to 6+ years.
I had been searching for a CHEK professional and was thrilled to find Tyler nearby. His assessments are extremely thorough and the programs he creates are thoughtful and truly personalized. I am about six months in now, and the progress is undeniable. My alignment has improved, my atlas rarely slips out, and I feel stronger and more capable than I have in years. If you are considering working with him, take the consultation call. It is the first step toward real, noticeable change.

Tyler, my personal trainer for the past six years, has been an absolute game-changer. His unique blend of humor and motivational skills has made every session enjoyable and effective. I have lost over 30 pounds and have kept the weight off while significantly increasing my strength. He has taught me good posture, proper walking technique, and flexibility — all improved through consistent practice. If you're looking for a trainer who makes fitness fun and inspiring, Tyler is the one.
Penelope Livingston
Tyler has been my trainer for over 5 years. When I first started my goal was to lose weight. My goal now is to live healthy. Through my partnership with Tyler I've learned about creating an overall healthy lifestyle that lasts. I'm stronger, have more energy, and have a healthier attitude about food. When COVID hit we transitioned to FaceTime and didn't miss a beat — we even brought in my husband and now we train together. Tyler's deep knowledge and dedication makes him a great asset to anyone improving their health.
Katie van Zyl
I've worked with numerous trainers and coaches over many decades, but Tyler is the first to truly and comprehensively incorporate all elements of my well-being — fitness, strength, flexibility, mental well-being, nutrition, sleep — into an actionable plan without it feeling overwhelming. On top of all this he makes every session fun and educational. I couldn't recommend him more strongly.
Todd Butson
I've trained with Tyler for a couple of months and his training is exceptional. His depth of knowledge for the human body is out of this world and is not just limited to physical training. He has provided guidance on weight loss through personalized workouts and nutrition strategies. Tyler emphasizes your well-being and encourages lifestyle changes that empower you to reach your full potential. To anyone looking for a personal trainer that values you and your time, I highly recommend Tyler.
Chyla Helean
Tyler is great to work with and has really helped on my fitness journey. I had some very specific requests on how I needed support for my fitness and nutrition goals and Tyler was very flexible and happy to support and guide me the way I wanted. It was also great to do the comprehensive assessment to take a snapshot of where my body and movement was so we could measure and track progress as I went.
