It is not uncommon, when watching Olympic runners bounding across the track in their typically graceful and relaxed manner, to feel as if they are floating on air. Their apparent effortlessness is due in no small part to their ability to coordinate (or synchronize) their feet, hands, arms, and legs such that they move in a cooperative, and even synergistic fashion. In fact, producing an efficient and powerful stride can be thought of as the act of coordinating (or synchronizing) the movements of your entire body from metatarsal to metacarpal, and head to toe, in such a manner that the whole becomes greater than the sum of its parts and muscular force, rather than being additive, becomes multiplicative.
