FIX.FIT · AI SPORTS COACH

See every
movement.
Train what matters.

A 5-node wearable sensor network captures your full-body motion in real time. AI coaching tells you what to fix, rep by rep — starting with boxing, built for every sport.

Down
to the
millimeter.

Raw inertial data becomes structured motion. Structured motion becomes coaching. Three stages, one pipeline — on-body, edge-first, in real time.

STEP 01CAPTURE

5 IMUs,
150 Hz, zero drift.

Clip the nodes on wrists, ankles, and waist. Nine-axis inertial data streams from your body to the hub the moment you move.

STEP 02RECONSTRUCT

Full-body skeleton,
frame by frame.

Five sensors. Seventeen joints. A real-time kinematic solver fuses 150 Hz inertial streams into a complete skeleton — angles, velocities, timing, all reconstructed without a single camera.

STEP 03COACH

Cues that actually
stick with you.

Rep-level feedback from a coach model trained on elite technique — delivered as voice cues in your ear and haptic taps on the node closest to the fix.

Five nodes.
One complete
picture.

Two wrists, two ankles, one waist. The minimum constellation to reconstruct full-body motion. Clip them on, hit record.

Cadence's holding at 118 — good. But power's leaking from the waist. Start the rotation from the floor.
04 · VOICE INTERFACE

Ask your body
to show itself.

Call out a movement. The nodes light up in the order they fire. You see the motion the coach sees — before you even throw the first punch.

“Extend left arm. Then step through.”

Built for boxing.
Built for every sport.

The sensor mesh is sport-agnostic. The coaching models aren't — each sport gets its own. Boxing ships first; the rest are in the pipeline.

06 · TWO SIDES, ONE TAPE

Same tape.
One shared
language.

The athlete sees their own movement. The coach sees the whole roster. Same data, different lens.

For athletes.

Stop guessing. Put on the nodes, hit the bag, get the one thing to fix before your next round.

01

Rep-level feedback

Every punch, every pivot — scored against your baseline and your archetype.

02

Track what moves

Velocity, rotation, cadence, guard integrity. Numbers that mean something.

03

Archive your training

Every session reconstructable in 3D. Compare week 3 to week 23.

04

Your coach, on-call

Voice cues between rounds. Post-session debrief with the exact moments to review.
