Do you have any health issues?

If you are age 50 or older and haven't exercised for some time, or you have chronic medical conditions, such as diabetes or heart disease, it's a good idea to consult with your doctor before beginning an exercise program.

It's also good to keep in mind that as you age, impaired balance, muscle weakness and other factors can limit your exercise capacity. Injuries may be more frequent, and recovery can take longer.

But that doesn't mean you shouldn't exercise or that you won't benefit from it. Before you start an exercise program, be sure to seek input from your doctor or an exercise therapist about how to create a program that's appropriate for you.

Besides aerobic, strength training and flexibility exercises, your doctor may suggest you include balance training exercises into your exercise routine.
