NOTHING HERE
IS RANDOM.
Every rep an athlete does with G3 traces back to a number. We test eight physical qualities, score them against the demands of your sport, position, and level, and the result decides what gets trained next. Not a hunch. Not a template. Not a workout someone liked on Instagram.
This is a real output of the G3 Performance Index — the same profile a G3 coach opens before writing a single session.
WE DON'T SELL WORKOUTS. WE MEASURE WHAT MATTERS, WE TELL YOU WHERE YOU STAND, AND WE TRAIN THE GAP.
ATHLETICISM ISN'T
ONE NUMBER.
It's eight physical qualities that show up differently in every sport and every position. We measure all eight the same way, every time, so a score means the same thing in January as it does in July.
How much force you can express fast, from a standing start — the quality behind a jump, a first step, a takeoff.
How well you use the ground. Short contacts, elastic return, energy given back instead of absorbed.
Getting to speed. The first ten yards decide most plays, and they're trained differently than top speed.
Your ceiling once you're up and running. A separate quality from acceleration — many athletes have one, not both.
Stop, re-plant, re-accelerate. Mostly a braking quality, which is why it's rarely fixed by more sprinting.
Strength relative to bodyweight. The engine underneath every other pillar and the base of durability.
Force through the arms and trunk — throwing, striking, blocking, pressing under speed.
Control, balance, and symmetry. The quality that decides whether the other seven hold up under load.
THE G3
PERFORMANCE INDEX
One number, 0–100, built from all eight pillars and weighted to the demands of your sport, position, and level. It answers one question honestly: how does this athlete perform right now, against a peer group we can actually name?
- ✓ Physical performance qualities, tested under a fixed protocol
- ✓ Your profile against a defined, disclosed comparison group
- ✓ The demands of your position, not the average of everyone
- ✓ Change over time, from the same test to the same test
- ✓ Where physical development should go next
- ✕ Sport skill or technique
- ✕ Tactical understanding or game IQ
- ✕ Game statistics or film
- ✕ How hard you work, or how much a coach likes you
- ✕ Whether you'll get recruited
Those matter. They're just not physical testing, and we won't pretend a number captures them.
SAME NUMBERS.
DIFFERENT ATHLETE.
Two athletes can post identical test results and still need opposite training. A middle blocker lives in the air. A soccer center mid lives in the last twenty yards of a sprint. The eight pillars never change — how much each one counts does. Pick a position and watch the weighting move.
FOOTBALL · LINE
Force and explosive power carry the profile. Max velocity barely registers — a lineman almost never reaches top speed.
FOOTBALL · SKILL
Acceleration and max velocity dominate. Upper body power is worth three points here and twenty on the line.
BASKETBALL · GUARD
Change of direction is the single heaviest pillar. The game is played in short, repeated, reactive bursts.
VOLLEYBALL · MIDDLE BLOCKER
Explosive power and reactive ability are nearly half the score. Almost no sprinting, constant jumping.
VOLLEYBALL · LIBERO / DS
Change of direction and movement efficiency lead. Same sport as the middle blocker, almost the opposite profile.
SOCCER · FIELD PLAYER
Acceleration, change of direction, and max velocity split the load. Upper body power is nearly irrelevant.
BASEBALL / SOFTBALL · PITCHER
Upper body power and movement efficiency are almost half the score. Sprint speed is close to noise.
TRACK · SHORT SPRINT
Max velocity and acceleration are over half the profile. Change of direction is weighted at zero — it never happens.
GENERAL ATHLETE
The balanced default. Used for middle school athletes and anyone without an established position — we don't specialize early.
FROM RAW NUMBER
TO REAL DIRECTION.
A stopwatch reading is not a score. Here's every step between the two — and yes, the steps run in this order, every time, for every athlete.
Fixed protocol, fixed surface, fixed equipment. Multiple trials, every trial stored — not just the best one.
Impossible and improbable values get flagged before they ever reach a score. Bad data doesn't get quietly averaged in.
We resolve the most specific peer group with a real sample behind it — sex, age band, sport, position, level.
The result becomes a 0–100 score against that group's distribution. Being best in a small room doesn't make you a 100.
Metric scores roll into pillar scores, and pillars are weighted to your sport and position profile.
Out comes the Index, the coverage, the confidence, and the development priorities the coach builds from.
THREE DEPTHS.
ONE STANDARD.
A full team combine and a high-performance profile need different tools. They don't get different math — the Index is device-independent, so a Level 1 score and a Level 3 score mean the same thing.
Built for schools, club teams, and combines. High volume, fast, no equipment barrier. The whole roster in one session.
- Vertical & Broad Jump
- RSI & Ground Contact Time
- 10-Yard & 40-Yard Sprint
- 5-10-5 Pro Agility
- Bench Press Velocity
Everything in Foundation, plus the strength and movement work that closes out all eight pillars for an individual athlete.
- Trap Bar Relative Strength
- Y-Balance Screen
- Medicine Ball Throws
- Flying Sprint Splits
- Extended Jump Testing
For athletes and adults chasing the last few percent. Instrumented testing, deeper profiling, tighter retest cycles.
- Force Plate Analysis
- Sprint Force-Velocity Profiling
- Isometric Mid-Thigh Pull
- Barbell Velocity Profiling
- Integrated & Wearable Data
SAME EIGHT PILLARS.
THREE DEMANDS.
A sophomore outside hitter, a 44-year-old who wants to ski without paying for it in April, and a candidate six months from selection are all measured on the same system. What changes is the standard we hold them to.
Middle school through collegiate. Testing establishes the profile, sport-position weighting sets the target, and the retest proves the training worked.
- Compared against
- Sex · age · sport · position
- Weighting
- Sport-position profile
- Also reports
- Next-Level Readiness

Beyond personal training. The same eight pillars, aimed at strength you keep, movement that lasts, and capacity for the life you actually live.

WE'LL TELL YOU
WHAT WE DON'T KNOW.
Most testing hands you a number and hopes you don't ask how it was made. Every G3 score ships with the evidence behind it — how much of you we actually measured, and how much we trust the result.
If we didn't measure a pillar, it's excluded from the score — not counted against you. The remaining pillars are reweighted to still total 100.
Eight of eight pillars is an official score. Below that, the report says so, in plain language, on the front page.
Trial count, variability, equipment, protocol, recency. Confidence never lowers your score — it tells you how much to lean on it.
No archetype, no strengths, no development plan from a half-finished assessment. It stays "pending additional testing" until it isn't.
Team, position, age-group, or G3 database percentile. We don't say "national" unless the data behind it is national.
Every trial, every score, every model version is kept. A retest creates a new record, so progress is auditable years later.
The G3 Performance Index is in active pilot validation. Weight profiles and scoring standards are provisional and versioned, every report discloses the model version it was scored under, and we will say so on the page rather than in a footnote.
THE NUMBER DECIDES
WHAT GETS TRAINED.
Every pillar leaves the assessment with exactly one instruction. That's the handoff from testing to coaching — and it's why nothing in your program is there by accident.
Well below standard, or a required pillar for your position is a critical gap. This gets the bulk of the block.
Functional but short of the target. Consistent work, measured against a defined retest date.
Meets the standard for your level. Enough exposure to hold it, no more — training time is finite.
Already past the next-level target. Protect it. There's little left to gain and something real to lose.
Alongside the current Index, we report how closely an athlete's physical profile aligns with the standard for the next competitive level — JV to varsity, varsity to club, club to collegiate. It's a physical alignment measure and nothing more. It is not a prediction of recruitment, selection, or success, and we won't sell it as one.
The Index identifies priorities, gaps, and the methods that fit them. It does not write your sets and reps. A G3 coach takes the profile, the calendar, the season, and the athlete in front of them, and builds the program. The data makes the decision defensible — the coach still makes it.
