Okey, thanks for the response
I just thought that there is very little volume doing only singles and because the other program (plan b?) already had singles and fives in a one workout I felt it would've been manageable doing separate days.
I might start with the 4-10x1 and try that to increase strength only for a few months. But at first I do 4 weeks of Pavel's russian bear program to get some muscle mass and conditioning.
