I have written about it in this thread a couple of times: Programming Improv - Block Training Thread
I have made steady progress over 6 cycles so far. Here is some date after 4 cycles: Programming Improv - Block Training Thread
´My rate of progress has been faster than during my prior pure ROP 2.0 cycle -- at least when I only count my pressing weeks. Each two week block offers the chance of beginner's gains. However, in absolute terms this might still take longer for achieving a specialized goal (suchs as pressing half bodyweight). But at the same time it was really sustainable.
The last cycle has been tough, mostly due to health issues (not training related). Without my current cold I would have reached 5x5 ladders with my former 4TRM bell in only 12 weeks of pressing. Now it will probably be 13 weeks. I have also moved up a bell with my LCCJ.
However, Pavel challenged me to build some muscle
before I proceed.
My current plan is therefore to run 1-2 blocks of BuiltStrong Minimalist with double bells before proceeding. That being said, I can easily see myself returning to two week blocks, for example alternating KBSF (double LCCJ) with hypertrophy grinds (for example, Fabio's die roll plan from the newsletter). I really like this approach, and feel that it helps with recovery and motor learning
Re GTG: Pavel writes in ETK that you could take all day and that rest periods are not specified on purpose. I have sometimes done so, or at least split my volume into 2-3 micro sessions. This works just fine. When I reached 5x5 I could then compress rest periods pretty naturally, although I usually took very long rests before. I like to do my presses without feeling rushed and fill my rest periods with household chores, playtime with my daughter, or cooking dinner.
