I think the thing that is refreshing with the whole CrossFit scene is that the information given is free (the only cost is if you subscribe to the Journal's, which are well worth it IMO), and the community is very open and friendly. There are many links to the companies that the CrossFit community recommends, for equipment, videos, books, etc, but there are a lot of links to low tech and/or homemade items (I made parallettes from directions on the XFit forum for about $30, and I am going to make some plyo boxes from directions from the same forum).
I think that too much of the fitness "advice" that was given was just a means of getting somebody to buy something (some supplement, equipment, clothing, book, etc). It's not unluck diet advice. To me, I think the world's shortest weight loss book would contain the following advice: "Eat less. Exercise more". But not too many people would buy it (something so simple couldn't possibly work), and how can you make any money from such a concept. Hence the watermelon diet, the cabbage soup diet, the Atkin's diet, etc.
To be honest, the whole CrossFit thing has been the closest to a "religion" or cult that I have experienced (and been part of). I have made a lot of contacts in the various Schools and units here in CTC, with other pers doing the training (or thinking about starting), and we have been exchanging advice/ideas/knowledge. I am quite the cheerleader for the concept, and while, yes, I could have found the same information in any number of (self-serving) books, it is pretty much all distilled into one source at the XFit site, and within the Journals. I'm sure that I will discover things that I don't agree with there, and I would like to think that I won't get "suckered" into some lame-ass purchase in the pursuit of fitness (a big honking Bowflex machine) or some other snake-oil things that the mainstream fitness magazines and books try to hawk as the end-all to getting fit.
The good thing that I can see coming of Xfit being adopted within the Army is that people will finally be taught how to do exercises properly (assuming units have pers taught via PSP staff or outsiders, such as by the Xfit certification seminars (there is going to be one at 3VP in August, according to the CrossFit.com website), vice the old "monkey-see, money-do" that was common in the weight rooms in the past (throwing weights around versus using strict form and control).
If it's a cult, I guess I'm part of a cult. At least the goal of this cult is improving my fitness, not promising me salvation via rectal probing by aliens
(and separating me from my cash)
