There's no need to buy expensive equipment or sign up for fancy gym memberships -- one of the most effective pieces of fitness equipment is already part of your home and office, and it's absolutely free. We're talking about the stairs, of course, and they might be just the thing to get you fit. After all, they're how Beyonce shapes up, so why shouldn't you use them as well?

The thing is, you know all this already, but I'm willing to guess that most of us are still loitering around the lobby waiting for the elevator to take you to the third floor. Do you take the stairs when you can? Or, when it comes to decision time, do you take the easy way up?

Last week, I asked you if your family is competitive or not. Here's what you had to say:

• 42 percent said absolutely -- you play to win.
• 24 percent said the only 'game' you played as a family was a race to the last pizza slice.
• 17 percent are occasionally competitive.
• 17 percent said you like getting active together, but you don't really compete.
