Learn to exercise like an astronaut

Going into space does havoc on the human body.

One of the biggest problems is muscle atrophy. When the body isn't working against the forces of gravity to move, or even stay upright, thereby putting weight on the muscles of the legs and back, those muscles can waste away pretty quickly. To combat this, astronauts in space have to work out for two hours a day to keep their muscles in check.

As you can see in the video below of astronaut Colonel Michael Hopkins training aboard the International Space Station, it's pretty intense.

If you'd like to be able to do what he does, Colonel Hopkins will be taking to Google+ on Thursday, February 6, at 9:15 a.m. PT to share some of his astronaut-training tips. He'll be joined by fellow astronaut Rick Mastracchio, and the pair will be streaming from space, onboard the ISS. Joining them Earthside will be astronaut Jeanette Epps, US Olympic bobsledder Curt Tomasevicz, CrossFit Games champion Rich Froning, Houston Texans football player Jared Crick and Peter Moore of Men's Health magazine.

To check out Colonel Hopkins' Train Like an Astronaut program, head over to the Facebook page. You can join the Google+ Hangout here. And don't worry if you're not awake in time to catch it -- you can submit questions via Google+ beforehand, and the video of the event will be available afterwards via NASA's Google+ page.
