Running, as movement pattern, is one of our favorites and has been a integral part of the history of human locomotion. Since the beginning of time, humans used running to keep up with migrating food sources that were critical for human survival and development. We also used our bipedal abilities to escape predation as one of our very first means of defense and life preservation. Today, we humans find this form of exercise is the single most accessible mode of fitness, costing us nothing but time and effort. 

Many of us acknowledge that going for a run allows us full control of our fitness experience. If we find ourselves in a heightened state of fatigue we can simple slow down to a walk, and when we’ve recovered, we can simply increase our cadence and open our stride to return to our original running pace.
