Thank you for your quick answer, Blake!
I understand and it's kind of cool to learn it that way with every little detail. But I have two little problems with following the program as described.
1. The book says something like "no weight prescribed for any exercise" and "none are intended to be performed with significant loading". I understand that with all classic lifts and all exercises of the progression. But why with the different squats, deadlifts and presses? It would be great to get generally stronger while learning the technique.
2. In about 6 weeks I have a 3-week-long trip and I thought a longer break while doing the progression would not be beneficial. That's why I asked for a shorter version of the program.
