"But I'm a fairly fit guy. If I can run, why should I spend my time walking?" Because cardiovascular fitness and metabolic fitness are not the same. So much of the important stuff, from a health perspective, comes from basic metabolic fitness, i.e... Conditioning your slow twitch fibers to use fat as their primary fuel. Without information to the contrary, the vast majority should assume that their metabolic fitness is currently weaker than their cardiovascular fitness & should spend the majority of their time rectifying that weakness.
