08. What exercise programs will be used in space to keep bodies fit and able to cope with the absence of gravity? (A K2S Question)

From The Space Library

Sometimes in space our muscles and bones get weak, so we do special exercises, like riding a stationary bike, to help keep our muscles strong. Under Earth's gravity our muscles have to work much harder, but in space the absence of gravity allows them to not work very hard at all which causes them to get weak. Exercise helps to keep our muscles working.
