I have found the Z-Health to be decently cost-prohibitive, then again, there were paradigm shifts in my own health-longevity bias that took place there that were worth the $$ IMO.
I really like the foot drills and will be replacing many of the Z-Health foot and ankle drills with them:
http://wellness.ndsu.nodak.edu/fitne...footDrills.pdf . After doing the foot drills followed by my Z-Health drills, I found everything to already be mobilized and ready to go. Those foot drills are a keeper.
What Z-Health (the DVDs) does is isolate all the particular joint movements, better than everything else (especially better than the WW program with all its extra movement "slop"). Without knowingly and purposely isolating a particular joint movement, the body will simply use another joint (that is likely hypermobile) to complete some semblance of the complex movement we're asking it to do. That's why I do both types (simple and complex).
Such as with Verstegen's stuff that was posted. Those movements are so complex that people could do them for years and never know that certain joint movements just weren't happening correctly, due to other joints "picking up the (lack of) slack".
Z-Health as a treatment modality--IMO, only Dr. Cobb has the wisdom and experience to do it well. Is it worth seeing him in a private session? Absolutely. Very well-spent money. Do I feel comfortable treating someone with it? Not really.
Any attempt (however bad) at joint mobility is better than nothing.
Last I heard from a CST jedi, So-non was bringing a suit against Dr. Cobb for stealing his joint mobility exercises (which he stole from someone else, as in the Slavs). Those yoga people better watch out, he's coming for them next...
