I have started this work out and love the idea and concept of it, seen many different variations and understand you tailor to suit yourself, however I would like other opinions on the days of the week bodypart a are worked and what would be optimal for recovery..

The most common layout I see is

Upper power
Lower power
Rest
Back/shoulders hyper
Legs hyper
Chest/arms hyper...
Rest

Now there is only 48 hours rest between chest/arms and upper power, I would rather have 72 optimally

So I came up with/found this

Upper power
Lower power
Rest
Chest/arms hyper
Back/shoulders hyper
Legs hyper,

But am unsure if doing chest arms the the following day shoulders/back will be ok?

Any thoughts any one played around with this?
Cheers
