What exercises do astronauts do?

Answer 1

There are several exercises that can be done in zero-G, any of which you can do here on Earth.

"Isometric" exercises, in which you use one muscle in opposition to another, require no equipment and can be done anywhere. Here's an example; press your two hands together. Push HARD. Relax. Push; relax. This is an "isometric" exercise, meaning "same movement". Here's another; Place your left hand on the inside of your right knee, and the right hand on your left knee. Use your arms to push your knees apart, and use your legs to pull them together. Or, reach down and grab your chair, and PULL yourself down into the chair. (Please DO NOT do this one in the seat of a fighter jet, as you might accidentally grab the alternate ejection seat handles!)

Other exercises that can be done on Earth or in zero-G involve flexing against a bungee cord or large rubber band, or using a resistance device like a rowing machine or a stationary bike.

Answer 2

Astronauts typically do a combination of cardiovascular exercises such as cycling and treadmill running, strength training using resistance bands and Weightlifting equipment, and balance and coordination exercises to maintain their physical fitness in space. They also engage in specialized exercises to counteract the effects of weightlessness on their muscles and bones.
