Just because you've been diagnosed with arthritis doesn't mean running is necessarily off your list of exercise activities, says Dr. White of the Arthritis Foundation. First you'll need a good pair of sneakers and perhaps orthotics to accompany them. Next, find a place to jog where the surface is flat and relatively soft. One option is to head to your local high school during their off hours and use the track. Not only will the surface give a little when you run, it also won't have the cracks, holes or debris that sidewalks or roads tend to have. Also, do remember to incorporate stretching into your jogging routine to prevent injury.
