The ergometer is like a bicycle without wheels, and the amount of exercise can be adjusted by varying pedaling strength. On the treadmill, astronauts can run while their bodies are held down using rubber straps. With resistance exercise equipment for weight training, a load can be applied even in space by using vacuum cylinders, and thus exercise can be done almost like weight training on earth. Make use of Google Earth's detailed globe by tilting the map to save a perfect 3D view or diving into Street View for a 360 experience. Therefore, astronauts exercise for about two hours every day using resistance exercise equipment for weight training, and aerobic exercise equipment such as treadmill and ergometer.

In space, however, there's almost no gravity, and no need for muscles and bones to support your body, so if you don't exercise, your muscles and bones will weaken.

On earth, even when you stand still, you resist gravity and support your body with your muscles and bones to maintain posture. Astronaut HOSHIDE Akihiko exercising with advanced resistance exercise equipment ©NASA Astronauts can exercise in space using equipment.
