Walk as much as possible. Whenever you are walking try to focus on long strides and quicker than normal pace.

You may work out an exercise pattern blending in well with your work schedule.

Take the stairs instead of the elevator. Walk up the stairs as quickly as you can. For a little variation, try slowing down and taking two stairs at a time to further strengthen your legs.

During breaks at work, walk the stairs, walk around the building or walk down the halls. Find any type of activity that keeps you moving during your break (you can sit at your desk and relax after the break!)

Whenever possible, stand instead of sitting. Even standing still will burn more calories than sitting.

Do not use the TV remote. Make a habit to get up from your seat, engage all your leg muscles, and walk over to change the channel on the TV.

When cleaning house, exaggerate your movements and make them big. Wash windows with a rag and make big arm circles and up and down movements. When cleaning, switch hands every so often to give your arms and body equal time on each side. Make long, rhythmic movements with the cleaner to get the heart rate up.

Plant a garden and work in it during the spring and summer. Gardening will involve your body in a whole range of movements and helps you in relaxing as well.

If you have children, or grandchildren, spend some quality time playing with them.

There can be some more of such activities like yoga and meditation varying amongst individuals and can be worked out as the idea is to remain active and boost up your energy level.
