Walking vs. Running

When starting an exercise program, or add on to an existing one, both walking and running are a great low cost, do anywhere, social activity.  They both boast many benefits and can be done just about anywhere outside, or inside on a treadmill.
For most people, the biggest difference between walking and running is the calories burned per mile or hour.  There is no doubt that given the same time and distance, a person will burn more calories running than walking.  However, distance should be the main consideration here, as people that walk tend to walk longer distances than people that run.  You can burn as many calories as running, but you need to put more time into it and cover a greater distance.  Since running is higher impact, it is tougher on the knees, hips, and feet.  If you are just starting out, you may want to start with walking and work your way up from power walking to running.  Both running and walking can be a social activity shared with one or more people.  There is always a time and place for exercising by your self, but working out with others has proven to be very effective.  You will inspire each other to keep going and not give up.  Power walking can provide an excellent workout and works a different set of muscles than running.  Some people choose to do both and alternate the days.  Alternating days will be easier on your joints while still giving you the high impact exercise that you like.
Both running and walking will provide the exercise needed to keep your body healthy.  It will also increase your energy level, improve your mood, and decrease your appetite.  Whether you walk, run, or do a combination, you are doing your body good and keeping it happy and healthy.
