Alright, I keep trying to get Kiefer to answer this one, and he keeps getting busy with other things.
(There's some REALLY exciting news I'm dying to share, having to do with DH being featured by one of the big muscle mags, but I can't yet...! We're really busy preparing for a lot of traffic... Be prepared to see a lot of new faces here in the forums!)
But what you guys need to realize is that Shockwave was designed in "chunks" that you are totally at liberty to mix and match together as you see fit. Doing tris and legs together, for example, is perfectly acceptable.
ALSO... you should know that the product we're building called "Shockwave Protocols" will be fully loaded with training plans for different splits along with the diet configurations that best fit these plans. So when you ask, "how do we do X days a week?" we're thinking, "damn we gotta get this product hammered out."
