I am afraid you misunderstood. Blitzing is mainly meant as a tool to increase the size and/or strength of all muscles/whole body. Also, it is meant to be used for a maximum of say 3-4 weeks and at minimum one day. Muscles can be tackled individually, but this is normally done with the intention to cycle through muscle groups.
Please note that this not 'overtraining on purpose', for the "overtraining" (overreaching actually) state is not the intention or an requirement for the effectiveness of blitzing.
CW's 'perfect 10' could be called blitzing, but so could Poliquin's 'one day arm cure'. (last one did not work for a lot of people)
Edit: 'Big Beyond Belief' would be a better example for it doesn't specialize on a few muscle groups. The gradual volume build-up is not neccesarily a component of blitzing however.
