Orion flywheel exercise device

The Orion flywheel exercise device (or Artemis Flywheel Exercise Device, FWED) is a compact, belt-driven flywheel-based exercise system developed for use aboard the Orion crew module as part of NASA's Artemis program. The device supports both aerobic and resistance exercise using a flywheel and cable mechanism to generate resistance proportional to user input, allowing movements such as rowing, squats, and deadlifts.
