    Exercising in Space

    Exercise is an important part of the daily routine for astronauts aboard the station to prevent bone and muscle loss. On average, astronauts exercise two hours per day. The equipment they use is different than what we use on Earth. Lifting 200 pounds on Earth may be a lot of work, but in space it is easy. The 200 pounds appear to weigh nothing. Therefore, exercise equipment needs to be specially designed for use in space so astronauts will receive the workout needed.
