Starting or maintaining a regular exercise routine can be a challenge as you get older. You may feel discouraged by illness, ongoing health problems, or concerns about injuries or falls. Or, if you've never exercised before, you may not know where to begin. Or perhaps you think you're too old or frail, or that exercise is boring or simply not for you. While these may seem like good reasons to slow down and take it easy as you age, they're actually even better reasons to get moving. Exercise can energize your mood, relieve stress, help you manage symptoms of illness and pain, and improve your overall sense of well-being. In fact, exercise is the key to staying strong, energetic, and healthy as you get older. And it can even be fun, too.
