It doesn't seem like that interesting of an article, just going on about how you should get thirty minutes of moderate activity at least four days a week.
The interesting bit is buried under the "Going Light" header. It mentions that one hour of light activity is equivalent to thirty minutes of moderate activity. Light activities include:
making photocopies, playing video games, coloring, sitting in a whirlpool bath, floating and "purposeless wandering."
So, just play video games for an hour a day, four days a week and you're fine!
