Walking is the best exercise (http://www.bellaonline.com)
Walking is a simple and effective way to lose weight, keep in shape and maintain good health.  The US Department of Health found in 1996 that walking helped increase the number of years you live - even if you only began walking in your later years.

Walking is a good form of exercise - because
Walking can be done with family, friends or by yourself. It can be done by most people.  You don’t need any special equipment apart from appropriate clothing and a pair of comfortable shoes. You can walk in most places both outside and inside. Many malls have walking programs that allow walkers to come in on off-hours and use the mall layout as an indoor track.

Why walking is good for your health
Walking at a brisk but comfortable pace for 20 to 30 minutes, three times a week increases the oxygen intake to the blood and strengthens your heart.  It improves the circulation and lowers blood pressure.  It helps you to lose or maintain your weight as a brisk walk burns up to 100 calories per mile – more if you are very overweight. Walking helps your body to regulate blood sugar, and cholesterol levels. Walking slows down the growth of arthritis and degenerative joint diseases.  It helps build bone structure so reduces the likelihood of osteoporosis developing.

Walking also helps
To relieve and prevent constipation.
Reduce premenstrual and pain during periods.
Lessen stress and will help you to sleep better. This is because walking generates the production of endorphins, which are a natural tranquilizer.
To reduce the risk of breast cancer.
To increase your energy levels.

All you need is a pair of comfortable walking shoes. Walking shoes - if you are walking 3 times a week shoes need to be replaced every 6 months, in order that you get the best support from them.

Remember
Don’t feel you have to walk a lot!  You want to build walking into your lifestyle and keep walking.  Everyone seems short of time so aim for a brisk walk of 15 minutes out, and then 15 back.  Check with your doctor before undertaking any new exercise program. Enjoy your walking!
