When finances are tight, expensive fitness gear is probably a luxury that doesn't make the monthly budget. You might be surprised, then, to hear that each and every day, you're walking right past one of the most effective fitness devices ever invented, a device that you are free to use at will, and one that will surely help you burn off the morning pastry you just downed.

I'm talking, of course, about the stairs. Most days, we pretend they don't exist and walk swiftly by in favor of the elevator. You might think there's no point, but research has found that short 10-minute bouts of intense exercise are actually very effective. Plus, taking the stairs can:

• Burn calories (duh!).
• Tone your legs.
• Score an energy boost by getting your blood pumping.
  

So tomorrow morning, don't walk on by. Conquer the stairs and reap the benefits of this fantastic -- and free -- workout.
