China’s astronauts are working up a sweat in orbit with a variety of exercise machines designed to keep them fit and fight the loss of bone density that comes with living in microgravity.
Video clips of the Tiangong space station‘s Wentian experiment module released recently by the China Manned Space Agency (CMSA) show astronaut Deng Qingming using a customized space cycling machine to exercise both sets of limbs.Â
Deng and his crewmates on the current Shenzhou 15 mission, commander Fei Junlong and Zhang Lu, are also using resistance equipment installed in the Mengtian experiment module for workouts that include rowing, squatting and pulling, which can help them strengthen muscles and bones in the microgravity environment of space.

The three-module Tiangong also has a treadmill, which has long been one of the main ways for astronauts to exercise to limit bone loss and muscle decay while in orbit.
The Shenzhou 15 astronauts launched to the Tiangong space station on Nov. 29 last year and plan to spend a total of around 180 days in orbit. Fei Junlong and Zhang Lu last week embarked on the mission’s first spacewalk.
