They exercise for up to 2 hours each day, so that their bones and muscles don't become weak.
astronauts like to exercise while in the ship
If astronauts don't exercise in space, weightlessness eventually causes there muscles to shrink?
their suits are very heavy.
there sweat starts to float in the space shuttle because once the astronauts are exercising in space they would start to sweat
I don't think that they do. However astronauts skeleton's do tend to lose some of their calcium while in space. This is because the lack of gravity means that the skeleton is not stressed. To try and prevent this calcium loss astronauts try and exercise hard (to stress the bones) if they are in space for a long period.
In a zero gee environment (weightlessness), the Human Body almost immediately begins losing muscle and bone mass. If they did not exercise, Astronauts returning from Space after a long stay on the Space Station would be unable to walk, and would have to be in a wheelchair for weeks before they could learn to walk again.
There's no gravity in space - this affects their muscles. Exercising keep the muscles toned.
