Our process
The 4-Stage
Model
Define Your Destination
PLANWe begin by clearly defining your desired outcomes and creating a detailed action plan. This foundational piece acts as the guide for everything that follows.
“A bad plan is better than no plan.”
Do The Work
PREPAREThis is where the magic happens. Our goal is to create the necessary physiological adaptations and build a mindset that will allow you to attack your performance goals.
“Sharpen the axe before felling the tree.”
Showcase Your Evolution
PERFORMPut your hard-earned efforts on display. This is where months of dedicated training become moments of excellence that define your career.
“Chase perfection, catch excellence.”
Evolve Relentlessly
PROGRESSReflect, recalibrate, reprioritize and re-engage. We evaluate your performance, identify margins for improvement, and push the envelope further.
“Greatness is a process, not a destination.”
The work and the proof
Trained hard.
Then measured.
The GPS difference
Progress you can see.
Most programs ask you to trust the process. GPS proves it. Every athlete is re-tested biweekly, and every gain is reported growth-adjusted — measured against what growing up alone would have delivered.
- Biweekly performance testing — six re-tests per 12-week block
- Growth-adjusted progress reports parents actually understand
- Every athlete profiled across all 6 performance pillars
- If training doesn’t beat growth, you don’t pay for the block
- Every re-test ranked against age-band norms, not against last block

Our foundation
6 Pillars of
Performance
Every GPS athlete is profiled across six performance domains — then trained where the data says the return is highest. This is what your athlete’s Blueprint looks like.
Strength
The foundation every other quality is built on — relative force production measured, trained, and re-tested biweekly.
Mobility
Usable range under control, programmed to what the screen shows — not a generic stretching circuit.
Speed / COD
Acceleration, top-end mechanics, and change-of-direction — the three-pronged model of elite speed.
Power / Force
Rate of force development: strength turned into explosive output on the field, ice, and court.
Mechanics
Movement quality under load and fatigue — what lets every other pillar express itself safely.
Neuro-Visual
Processing speed, reaction, and decision-making under pressure — the pillar most programs never train.

Priority qualities · where the block’s volume goes
The two lowest pillars set the training emphasis — not a coach’s hunch, and not whatever the athlete already likes doing.
This is a sample profile, not a real athlete. Your athlete’s radar is built from their own tested numbers.
Zero-risk training
Three guarantees.
All in writing.
We control the measurement, so we can put the risk on us. Every guarantee below is settled by your athlete’s tested numbers — not by our opinion of how the block went.
Guarantee terms are defined in the enrollment agreement · 90%+ attendance & tracking required
Blueprint Clarity Guarantee
If you walk out of your Blueprint assessment without knowing exactly what your athlete needs, it’s free — and the report is still yours to keep.
12-Week Improvement Guarantee
A measurable gain in your athlete’s priority qualities by Week 12 — with 90%+ attendance and tracking — or they train free until there is one.
The Growth‑Adjusted Guarantee
We measure your athlete against what growth alone would have delivered. If training doesn’t beat growing up, you don’t pay for that block. A promise we can only make because we measure growth itself.

Athlete results
Don’t take our word.
Take theirs.
Tremendous growth in my explosiveness, strength, and running mechanics. Garrett is always keen to new technologies — we corrected my running with in-depth video analysis and used instruments to measure power output and muscle fatigue. He caters my workouts to my position and is always conscious of how he can improve our sessions.
He pushed me to peak performance heading into my final season. I started training with Garrett to get ready for my final year at Western Kentucky. Every workout was challenging, and whenever I asked about my form or a movement he had insightful, detailed answers. Anyone looking to better themselves — for sport or for life — should train with Garrett.
More GPS athletes
A specific plan every session to make me faster and more explosive. Garrett is a high-energy, extremely focused S&C coach — skilled in building a plan tailored to your exact needs.
An unprecedented program that took my game to the next level. Working with Garrett for three years helped me take real strides in my development.
Training with Garrett changed my trajectory as an athlete. It played a major role in giving me the chance to compete at the Division I level.
Real progress with my body composition and strength — in just two months. He built QB-specific drills and workouts for me that made me a better quarterback.
