If you look at someone who is able to walk the same pace as he or she can run, walking should consume as many, if not more, calories as running. It may also save some wear and tear on your joints. Surprisingly, a recent study in the journal Medicine & Science in Sports & Exercise found lower rates of arthritis and hip replacements in runners than walkers. That result, though, likely stems from the lower body mass indexes of the runners than their walking counterparts.
Running is a great way to burn calories. But if it doesn't work for you, walking can be a great alternative. In your case, it sounds like walking is just what the doctor ordered.
