Health Watch -- Working Out
Health Watch is a Public Service of the Office of News and Publications and is intended to provide general information only and should not replace the advice of a medical professional. You should contact your physician if you have questions about any of these topics.
How much exercise do you really need? New government guidelines call for at least a half hour of exercise most days to help prevent chronic diseases like heart disease or diabetes. You'll need an hour of exercise most days to avoid gaining weight, and more than that to lose weight.
Dr. Benjamin Levine, a sports medicine expert at UT Southwestern Medical Center at Dallas, says your goals will determine the frequency, duration and intensity of your workout. The important thing is to exercise. Don't worry if you can't live up to these guidelines.
Health Watch is heard Monday through Friday nationwide on the "Stardust" format of ABC Satellite Radio. Call your local radio station and ask if they carry the program.
