Recording tips

  • Film from the side at hip height.
  • Keep the whole body in frame — hands to feet.
  • Move slowly so each opposite reach is clear.
  • Keep it under ~30 seconds.

Better lighting and a full body in frame give the AI a more accurate score.

Lower back liftingFix

Keep your low back pressed into the floor as you extend — shorten the range if it lifts.

Rushing the reachWatch

Slow down — the control is the point. Pause briefly at full extension.
