Artemis II astronauts have fitness lessons for everyone

The Artemis II crew — Christina Koch (left), Jeremy Hansen, Victor Glover and Reid Wiseman — have to share tight quarters aboard the Orion spacecraft on their way home. But even with limited space, they can still get a solid workout in — thanks to a very special piece of equipment.

The Artemis II astronauts don't have a lot of space to exercise. That's why they've got the flywheel — a small device that can be used for strength and cardio workouts.
