How To Clip Your Nails In Space & More Gravity-Defying Astronaut Beauty Secrets
Astronaut Catherine Coleman, Sandra Bullock's space mentor for the Oscar-winning "Gravity," talks beauty, fitness and hair care in Zero G
If that's not motivation enough, having 100 scientists, engineers and doctors on earth monitoring your every move helps. That, and the fact that your gym is rigged with space Nautilus and it's approximately 17 inches away from where you eat, sleep and work. "Let's just say your motivation is through the roof," Coleman adds. "We're exercising up there at least five days a week and it's not hard at all."
What does the ISS gym look like? There's a weightlifting machine that simulates gravity through cylinders within cylinders (in zero g, astronauts can adjust the weight from six to 600 lbs.), a treadmill (hovering in the air, just like the astronauts) and a mechanical bicycle strapped to the floor. "We also do squats, dead lifts, heel raises, bench presses, sit-ups ... anything you can do with a bar for leverage," says Coleman. We aim for one and a half hours a day, because the other 22 and a half hours of the day, you're resting."
