Klorg, no offence but if that's your situation then I don't think WSSB is for you for now. WSSB requires maxing out / challenging your PR on lower body and upper body once on each every week, which could be too much for you in terms of training experience. If you follow WSSB truly, meaning having GPP/sport/strongman training in between weightroom days, it could be too much sometimes even for intermediate level lifters.
May I suggest the following:
1) WSSB without Maxing - Do the ME exercises with 3-5sets of 3-5reps that is close to your PR but NOT challenging your PR every week as suggested in the article. Switch set/rep and chocie of exercises every cycle.
2) Full body programme to start with as I originally suggested. Mix in WSSB's exercises in your programme and graduately starting WSSB.
My 2cents and hope it helps,
