If your New Year’s resolution is to get healthy, there’s no better place to start than at your desk (we do spend about eight hours a day in the office, after all). We asked Paige Waehner, a certified personal trainer and author of “The About.com Guide to Getting in Shape,” about simple steps to keep your desk from becoming the death of your diet.

What are three things that can be done at your desk to stay fit?

There are a variety of things you can do while working to stay healthy and keep the circulation going. Sit on an exercise ball for a few minutes at a time throughout the day. It’s a great way to improve your posture and sit in a more active way. Make sure you take frequent breaks to stand up, stretch and walk around —make it a habit to get up every 45 to 60 minutes. Set an alarm if you need a reminder. And finally, stand up whenever possible — when you’re talking on the phone, going through your mail or doing other tasks that don’t require sitting.

What if you aren’t at your desk all day? Any other tips?

You often have to be creative to find ways to move more. Using the restrooms on another floor and taking the stairs is one way to sneak in exercise. Other ideas include walking to your co-worker’s desk to talk to him or her instead of using e-mail, parking your car at the end of the lot each morning, and using your lunch hour to take a walk.
