You progress from 3x(1,2,3) to 5x(1,2,3,4,5) on your heavy days - only when you achieve that, increase the weight.
If I may advise you: add systematically one rung a week to your heavy day's volume, for a total of 13 weeks.
Could you please explain this in detail?
I'm a bit confused here, because if I lay out a plan like that, I'll always come out with less than 13 weeks.
(1,2,3) x3 / (1,2,3,4) x3 / (1,2,3,4,5) x3 / (1,2,3,4,5) x4 / (1,2,3,4,5) x5 = 5 weeks
(1,2,3) x3 / (1,2,3) x4 / (1,2,3) x5 / (1,2,3,4) x3 / (1,2,3,4) x4 / (1,2,3,4) x5 / (1,2,3,4,5) x3 / (1,2,3,4,5) x4 / (1,2,3,4,5) x5
= 9 weeks
(1,2,3) x3 / (1,2,3,4) x3 / (1,2,3,4,5) x3 / (1,2,3) x4 / (1,2,3,4) x4 / (1,2,3,4,5) x4 / (1,2,3) x5 / (1,2,3,4) x5 / (1,2,3,4,5) x5 = 9 weeks
EDIT: Nevermind... finally figured out myself
