See the engine work. No camera required.
This plays a synthetic figure through a supported march and feeds it to the exact same repetition state machine the live coach uses. Nothing here touches your camera.
This runs the exact repetition state machine used by the live coach — fed a synthetic figure instead of your camera. The counter only advances on complete, calibrated repetitions.
What you’re watching
The figure’s knee lift is normalized (pelvis-centered, torso-scaled), turned into a calibrated excursion, and passed to the repetition state machine. A rep only counts when the movement leaves neutral, reaches a real peak, and returns — partial or jittery motions are rejected, exactly as they would be with your camera.
Ready for the real thing? Open the coach — it asks permission before the camera ever turns on.
