You're in the mood to do a quick workout, but are at your office or home, with no workout in sight? No problem: You can now stream exercise videos over the Internet with Netflix's Watch Now feature, free with an existing subscription, and it doesn't mess up your DVD queue. For instance, the 10-minute exercise videos could easily be done in your office during a break. And after that workout, you can reward yourself with a 20-minute episode of The Office.
