Okay, so once you wipe the drool off the package, pull open the bubble wrap, and read the legalese, here's what you find.
4x7 comes as a set of four DVDs, one for each day in the cycle. Two of the DVDs provide detailed (and I mean detailed, pointing out each of the key components of structure in each exercise) explanation of the exercises contained within three circuits. The other two DVDs provide compensatory Intu-Flow and Prasara. Also included is a 28 day program schedule, so you know which disc to plug in for any given day.
The theory is repeated on all discs, and the exercise breakdown is repeated on the first two with the circuits, to minimize the need for disc swapping. So you'd really only need to take one with you to your training area if you needed to do some review there (presuming you haven't memorized the sequence)
I'm a little hesitant to toss too much detail out there about the actual contents. I'm of the opinion that it would be kinda cool to wait a month or so, for the results of the Transformation Challenge to come out, before getting into too much detail. I believe this is one that will be more fun to talk about after some folks have done the full 28 day program.
I will say that watching the circuits on the DVD reminded me of just how much fun (i.e. tough) a few pieces of those same circuits were in a Prasara workshop I attended with Coach Sonnon in April. Seeing the new pieces, and looking at the theory, I'm quite impressed at how it fits together. Get ready to develop your relationship with gravity! The heavy cycle looks like it would kick most people's tails!
There's something primal to it, too, in that it targets movement patterns that would serve our forest-dwelling ancestors quite well. It might be useful to look at it that way. In my exploration of gyms in my neighborhood thus far, it seems more likely that I'll find a suitable tree limb in a park before I find a place with an appropriate pullup bar, with enough space around it to do the circuit. (I realize my mistake, though, that I might just need to focus on finding older gyms.)
So, just from reviewing the video, this looks to be a most promising program. The real treat, though, will be seeing the results of the sweat, from its application.
