Recording tips
- Film from the side so the banana-shaped body line is obvious.
- Keep shoulders, hips, and legs in frame.
- Hold still — a short clip of the hold is enough.
- Keep it under ~30 seconds.
Better lighting and a full body in frame give the AI a more accurate score.

Press your low back into the floor — shorten the lever (bend knees) if you can't keep it glued down.
Too tucked / no tensionWatch
Lengthen slightly into a hollow shape — shoulders and legs off the floor with abs braced.
