The movement
Edit the drawing
From the camera, drag a joint: the bone above it turns and everything below comes round with it, every limb keeping its length. The hip drags the whole body. The other keyframe sits behind, faint. In a side view the far limbs are the dimmer handles. From above, the camera sits at the bottom of the picture: drag a joint down to bring it toward the camera, up to take it away. Isometric is a look at both together, not editable.
Equipment and shapes
Drag a prop in the drawing to move it: the square handle at its corner sizes it and the round one above it turns it (shift: freely, not in steps of five degrees); Delete removes the one picked. One fixed to a body part moves and turns with it, and keeps the place you gave it on that part; kept level, it goes with the part but does not turn — a kettlebell hanging. One that stays put can be somewhere else at the end: tick it, show B, and move it. A band, strap, stick or line runs between two ends: drop an end on a joint and it is fixed there.

What is measured
One card a measurement: what is measured and how it is read, what it is for, when it must be right and between what, and the faults on either side. Classify the reps on the right and every fault's row says where its number should sit.
The start position
What the coach waits for before it says or counts anything: the start position, held still and seen. In the file: ready (what counts) and defaults.readyMs (how long).
Measures you have not built
Every measurement the camera could read over these landmarks, tried against the reps you classified: the ones where the reps you marked with a fault stand apart from the clean ones, above the model's own wobble. Add one and it becomes a card above with a fault on it, ready to word.

The file
The whole file as it stands. It can be edited here too; Apply reads it back into the form.

What the lanes show · at this moment · the cues · a demo film
The top lane is the reading the rep is judged on; below it one lane per band, then the coach's cues at the moments they would have been said. Tap anywhere to go to that moment.
At this moment
Every cue, in order
A demo film
The clip drawn over and voiced after the fact: the skeleton, the counters and every cue on the picture, and on the sound the coach's own voice and the tones at the moments they would have played.
The reps
Each rep the coach saw in each recording — counted, or an attempt it dropped — with why, and every fault it had on the screen inside it. Classify each rep as you see it on the video: clean, the faults it really had, a fault the exercise does not know yet, or not a rep at all. Every rep in the recording is listed, however many a set asks for. Your verdicts stay with the recording while it is loaded and go into its trace file when you save it; removing the recording, reopening the page or changing the exercise starts again with none. The numbers on the left follow them.
