Back in our cavemen days, we spent almost every waking moment in a quest for food. Our bodies were ready at a moment's notice to spring into action if prey was at hand.

These days, we still spend a good deal of time in a quest for our next meal ticket, but the difference is that for a lot of us, that time is spent hunched over a computer. Of course, getting out and exercising daily along with eating well is the best way to stay healthy in a desk job. But what else can you do to keep yourself healthy during your workday?

9 am: Do some calf raises - while sitting at your desk, lift your heels up and down off the floor at least ten times. This will keep blood circulating in your legs and help avoid swollen feet and varicose veins.

10 am: Skip the coffee refill and have a glass of water - H20 is absolutely vital to the efficient functioning of our bodies. Don't neglect it! 64 oz per day is a good target to set.

11 am: Stop and breathe - push your chair away from your desk and breathe in and out deeply at least 10 times. This simple exercise will help you refocus, clearing your mind so it can properly work on the tasks at hand.

12 pm: Hit the stairs - find a stairwell and head up and down it a few times. Keep that blood circulating!

1 pm: Get laughing - take a few minutes to do a google search for clean jokes. A dose of humor is a great mood-lifter and can help change the course of a gloomy day.

2 pm: Do some spinal R&R - to help realign your spine from its hunched over position, sit up straight, then roll your shoulders back and let your head fall back as far as it will comfortably go. This is a great tool for helping relieve the tension that can build in your back over a day of desk work.

3 pm: Skip the Cheetos - your tummy is rumbling, but it's time to gather all your self-control and reach for an apple instead of the vending machine. Fruit is a great source of fiber and vitamins and can provide just as much energy as those damaging packaged snack foods.

4 pm: Spend a minute to dream - take three minutes to dream about all the big things you want to accomplish in your life, whether a new car or a new home in the Bahamas. It's easy to get caught up in the day-to-day, so don't forget to look at the big picture of your future for inspiration.

5 pm: Smile! It's time to go home - don't let traffic get you down, find a good radio station and settle in for the ride. The rest of the day is yours to enjoy.
