Performing resistive exercise in space is the only way that astronauts can maintain their physique, given the lack of gravity which is something the 'Orpheus' suit enables.
The 'Orpheus' offers a total body workout and enables the wearers to go about their daily tasks while wearing the suit in order to help them keep up with their physical needs even when they are in space.
The 'Orpheus' suit is the design work of Mehmet E. Ergül and is a far more versatile option than what is presently in use by astronauts at or heading to the International Space Station. The suit can be programmed in order to be augmented to suit individual needs of different astronauts and wearers. Have a look at the images about to see what the 'Orpheus' suit looks like.
Also, take a look at the video to see James May, of Top Gear fame, trying out the current space suit that keeps the astronauts alive out there – it's clearly not for the faint of heart!
