Artwork no. 792 «Preview Size» Title: Zero Gravity Fitness Finished: February 16, 2021 In space, astronaut should have exercise regularly to prevent muscle weakening caused by zero gravity. This treadmill was installed on Node-3 so astronaut can use it for exercising. Since no gravity available to keep astronaut having firm step on the treadmill, a harness was used to keep astronaut stay on top of the treadmill. Also in zero gravity, sweat will not drop down but stay as droplet, unless it being swept with other object like body limb for example.
