Running and walking may be very similar activities in terms of biomechanics but they are very different in other aspects. These aspects may include elements such as calorie expenditure, impact, efficiency and even the recovery periods. Although walking is good exercise for those who are just starting to workout and previously did not do any exercise, it is inferior to running in terms of total benefits. Those who start their exercise by walking are encouraged to gradually increase the intensity to a jog and then a run if they want to achieve the maximum benefits associated with exercising on a regular basis. This article will compare running and walking in an effort to help the reader understand the differences and how they can be exploited to tailor a training program to help the individual to achieve his personal goals.
