Water aerobics is another popular form of exercise. This can be anything from walking or running against the resistance of water, to doing jumping jacks in the water. There is a debate about whether or not swimming burns as many calories as other forms of exercise. But one thing is sure: the effects on your health are just as great.

FAITH LAPIDUS: Whatever kind of exercise you choose, experts agree that you should start small and work your way up. Start by exercising ten minutes a day two times a week. After a few weeks, increase your time to fifteen or twenty minutes, and increase the number of days.
Next, try to increase the intensity of your workout. If you have been walking, try walking faster, or take turns between walking and jogging. And try not to forget those muscle strengthening exercises. The more time you spend exercising, the more health benefits you get.
Health experts advise people who have been physically inactive to have a complete physical exam before beginning a new exercise program.
BOB DOUGHTY: If one of your goals is to lose weight, you will also need to change how and what you eat. To lose weight, you must use or burn off more calories than you take in.
A pound of fat is equal to about four hundred fifty three grams or three thousand five hundred calories. To lose that fat in a week, you have to burn off at least that amount in calories or eat that much less. The best thing to do is to combine both ideas. Eat fewer calories and increase your activity so that you burn off more.
