Fysiio · live biomechanical model

Movement,
computed.

Every point you see is riding a real biomechanical model — 30 clinical degrees of freedom, solved live.

// what the cloud is drawing

Not filmed video. Every exercise is solved by a movement engine from clinical joint angles and normative range-of-motion limits — then re-projected everywhere you see it.

30 degrees of freedom

A whole library of movements, rotate-able, scrub-able, shareable as a link. No two look alike because none are canned clips.

The same solved data renders as an illustrated body, a 3D model, or clean lines — from four camera angles you can drag around.

The particles are the abstraction. Here's the same engine as you'd actually use it.

Illustrated body
Glute bridge with the muscle-activation view on — clinically authored activation estimates, not measured EMG.

3D model
The cat-cow you saw above, rendered as a lit 3D figure you can orbit around.

Pose it yourself
The creator exposes the same joint-angle sliders the engine reads — author a movement from scratch.

Stop watching the abstraction.

The cloud is one exercise. There are sixty-four more, and none of them are video.
