🔧 Fix this

Ideas a builder, maker or community group could start on:

  1. A mobile app that uses AR to overlay the correct pivot point on a user's knee when they stand next to a machine
  2. A standardized, universal sticker kit for gym equipment that clearly marks the axis of rotation with a visual target
  3. A video database or QR code system on machines that shows a 3D animation of proper anatomical alignment
