3 wks PRRS, 3 wks of FD/FS, 3 wks PRRS again. That was in the past, then Eric created a hybrid version some time back. That looks like this.
I believe what you are referring to are days to combine FDFS damage protocol with a SHOCK saturation method. An example is below:
-Bench Press…2 x 3-4 (3/0/X tempo)
-Incline Press…2 x 5-6 (6/1/1 tempo)
-Incline DB Flye…2 x 7-8 (2/4/1 tempo)
-REST PAUSE: Bodyweight Dips (1/0/1 tempo)...1 x max reps, rest 15 secs-max reps, rest 30 secs-max reps
-SUPERSET: Cable Crossover/Bodyweight Push Ups...2 x 16-20/max till failure
