of your own body.

Nobody feels what you feel.

The loop that makes you the expert

Assess. Train. Arrive.

Most people train blind and hope.

Record the movement.

Turn footage into findings

Replay the clip.

How a session actually goes

Wednesday, 7:12 pm. Your right chest is tight.

Five minutes later you know more about that pain than three months of guessing gave you.

  1. Point at it instead of guessing

    You create a challenge — no name, no form. Rotate the 3D body, zoom into the chest, tap the exact spot. 6 out of 10.

  2. Get an idea what to do

    Tap that region on the pain map and Mobility Log suggests matching videos from Luke Brandenburg's channel. You pick a drill.

  3. Set the rhythm

    Timer: 3 rounds, 30 seconds per side, 15 seconds rest. It beeps and buzzes on every switch — no need to watch the screen.

  4. Film it — and catch the insight mid-rep

    Camera on, recording. Something clicks halfway through, so you type it straight into the field below the viewfinder. Timestamped onto the session. Then rate how it felt.

  5. Keep what worked, watch it fade

    In the diary you pin that observation as a key outcome. Next check-in it's 3 out of 10 and the region visibly cools down. For your physio: one briefing with observations, pain history and every clip.

That's the whole loop: mark it, understand it, train it, record it, keep it. Two minutes of work per session — and a body you can finally explain.
