having done crossfit and workouts similar to the ones planned in the article, i disagree. crossfit does make use of some of the principles outlined in the article, yes. but you could say that about almost any workout scheme, including 20lb weights balancing on a bosu ball. there are bound to be some similarities. crossfit is frenetic, with exercises that vary daily. this routine is advocating a more static set of consistent core exercises. crossfit mixes up the styles of exercises pretty frequently -- some are strength, some are endurance, some are timed, etc.. again, this routine is more about slow, steady, consistent improvements on a single set of exercises. crossfit is a single workout track that gets everyone "fit", while this routine is pointing out that you need to approach the exercises differently based on your personal goals. etc etc.
