True, but it also depends what your workouts are like. If you're doing strenuous doubles daily, yes, you absolutely need a full rest day. A varied program of, say, yoga, weights, running, swimming? Maybe not. You have to order your workouts properly, but my guess is that the vast majority of people aren't working hard enough to *need* a rest day the way that serious athletes do (having trained at that level for many years, I know it well).
