Sport-Specialist Coaching Staff

Each coach holds sport-specific certification. No generalists. Every athlete trains with a sport specialist.

Seven disciplines

One system.
Every sport.

The same assessment-to-program architecture applies across all seven sports. What changes is the specialist, the movement vocabulary, and the performance markers.

Train
smarter.

Velocity-based training. GPS tracking. Force plate analysis. Every rep measured — every session on record.

The Method

Four phases.
One outcome.

Every athlete enters through the same door: a sport-specific assessment. Everything that follows is built from what we find — not a preset program off a shelf.

Phase 01
Assess

A 90-minute sport-specific physical and movement assessment. Speed, strength, power output, mechanics, and sport-IQ benchmarks captured on entry. No athlete begins training without a baseline.

Deliverable: Athlete Performance Profile
Phase 02
Program

The coaching staff builds an individualized development plan from the assessment data. Sport, position, timeline, and target metrics drive the program architecture. Training starts on day eight.

Deliverable: 12-Week Development Plan
Phase 03
Train

Sport-specialist-led sessions, 4–5 days per week. Velocity-based strength work, position-specific skill development, and sport conditioning. Progress data captured every session — not every four weeks.

Deliverable: Weekly Performance Report
Phase 04
Elevate

Mid-cycle reassessment against the entry baseline. Metrics reviewed, program adjusted. At cycle completion: a final performance report and recommendation for next-level placement — combine, combine prep, program, or scholarship pursuit.

Deliverable: Final Performance Report

Acceleration Analysis

The split that
defines careers.

Most programs measure the 40-yard total. FLEXUS measures the four phases inside it — because the milliseconds between drive, transition, top-end, and deceleration control tell you exactly what to fix.

Phase 01 · 0 → 10 yd
Drive
1.52s
Top 8%
Block start, hip drive, and first-step acceleration. Where separation starts.
Phase 02 · 10 → 20 yd
Transition
1.09s
Top 12%
Drive mechanics into upright top-end posture. The zone most athletes lose time in.
Phase 03 · 20 → 30 yd
Max Velocity
0.95s
Top 6%
Peak stride length at top-end speed. Separates draft prospects from everyone else.
Phase 04 · 30 → 40 yd
Decel Control
1.01s
Top 15%
Holding mechanics under fatigue. The phase most combine programs don't train.

Athlete Intelligence Platform

In your
hand.
Every rep.

Every sensor feeds the platform. Every rep, every split, every session — captured, scored, and surfaced to the athlete in real time. The dashboard shows you where you are. The coach shows you what to do about it.

Live Session Metrics
Velocity, force output, ground contact time, and power asymmetry — updated every rep, visible mid-session on the coach dashboard and in your app after cooldown.
12-Week Trend View
Every metric plotted against your entry baseline and your 12-week target. You see the arc. You see the gap. You see exactly how many sessions remain to close it.
Program Calendar
Your development plan, session by session, in the app. Every session has a focus, a load target, and a velocity threshold. You know what's coming before you walk in.
Coach Annotations
Coaches flag technique corrections, load adjustments, and benchmark alerts directly in the app. No WhatsApp. No memory. Every note lives on the data it references.

Performance Science

Every sport demands
a different power.

The force-velocity curve is the most important concept in sports science. It defines what type of power your sport requires — and most training programs ignore it entirely.

Max Force Strength / Power
Max Velocity Speed / Quickness

FLEXUS maps each athlete's current F-V profile on entry and builds the 12-week program toward their sport's optimal zone. Training that ignores the curve doesn't build the right athlete — it builds the wrong version of one.

Athlete Profile · Sample

The fingerprint
no two athletes share.

Every athlete's performance profile is unique. Six axes. Six dimensions. The FLEXUS assessment maps the exact shape of your athletic capacity — and the 12-week program trains toward your sport's optimal signature.

THE DATA DOESN'T LIE.

Every millisecond is measurable. Every rep is on record. The program is built from what the data finds — not what the athlete believes.

Coaching Staff

Sport scientists.
No generalists.

Every coach at FLEXUS holds a sport-specific credential and a performance science certification. Former professionals who read the data — not trainers who guess at it. The coaching staff interprets the platform; the athlete executes the program.

Performance Science

Technology
is the
edge.

Every session at FLEXUS is instrumented. Velocity sensors. Force plates. GPS tracking. 3D biomechanical motion capture. The data drives the program — not the coach's intuition. The coach interprets the data.

Athlete dashboards update in real time. Every session logged. Every metric tracked against the entry baseline and the 12-week target.

Velocity-Based Training

Linear position transducers and inertial measurement units capture bar velocity, peak power, and force output on every rep. Loads are adjusted in real time to the velocity target — not a percentage of a max.

LPT · IMU · Force Plate
3D Motion Capture

Twelve-camera Vicon system captures biomechanical data at 250 Hz. Sprint mechanics, throw kinematics, jump landing patterns. Technique faults identified at the sub-frame level — not by eye.

Vicon · 250 Hz · Full-body marker set
GPS & Inertial Tracking

GPS-IMU wearables capture distance, speed zones, acceleration events, and player load in every field session. Sport workload is quantified. Overreaching is detected before injury — not after.

Athlete Intelligence Platform

All sensor data routes into a single athlete profile. Coaches see session history, trend lines, and flag alerts. Athletes see their dashboard in the app. Program adjustments propagate automatically from the data.
