Endurance and Aerobic Exercises
Endurance/aerobic exercises increase your breathing and heart rate. They improve the health of your heart, lungs, and circulatory system. Having greater endurance not only helps keep you healthier; it can also improve your stamina for the tasks you need to do to live and do things on your own -- climbing stairs and grocery shopping, for example. Endurance exercises also may delay or prevent many diseases associated with aging, such as diabetes, colon cancer, heart disease, stroke, and others, and reduce overall death and hospitalization rates.
Walking, dancing, biking, and swimming are all good options. Also check out your local senior center, rec center, Y, or local fitness center for classes that are appropriate for you. Many centers offer exercise classes for seniors. They're out there if you look.
