Working in an office doesn't mean you can't stay fit. Here are two exercises that will help you burn calories, have more energy and build strength.

For Your Lower Body:
1. Stand in front of a stable office chair with your feet shoulder width apart. Slowly sit down in the chair, focusing on using the muscles in your legs. Without using your hands, return to a standing position.
Do three sets of 8 with a minute of rest between sets. If you are tall and your hips are lower than your knees when you are sitting, don't go all the way down. Just use the chair as a guide.

For Your Upper Body:
2. Start seated in the chair. Slide forward until you are supporting yourself by your arms with your legs out in front of you. Bend your elbows and lower yourself down a few inches and then back up.
Do three sets of 8 with a minute of rest between sets.
