San Diego, California - Some of the excuses older folks have for not exercising are so far off the mark that they reveal a deep seated guilt about their sedentary lifestyles, according the Association of Mature American Citizens.  "I'm not getting any younger," they'll say.  But the fact is that a regimen of exercise will actually make you feel younger.

You don't have to run a marathon, but maybe you can get up out of that armchair and take a brisk walk, says AMAC.  You'll be amazed at the benefits.  We all know that exercise is good for your heart.  But did you know that it can lower the risk of dementia and Alzheimer's disease.

Meanwhile, if you are suffering from a chronic illness that has you "grounded," there are special aerobic and stretching exercises you can do that can help improve muscle health.

Be sure to check with your physician before you start in on any exercise program.  In fact, the doctor may have suggestions on what types of workouts would be best for you.
