ok im not sure what the 4SB entails but WSC is basically pick 4 ME uppper body movements and 4 ME lower body
here ill lay it out for you...
1. dont DL and SQ in the same session on ME day, itll be exhausting. it can be done but i wouldnt do it
2. you can use DL as a max effort lift, i wouldnt tho. use a variation of it...
DL vs bands / reverse bands
DL w defeceit / w or w/o bands
DL from blocks / mats
and pick some squatting exercises or something like
sq vs bands / reverse bands
variation of different bar sqs like safety bar
pick 4 ya kno?
and as far as what exercises "work" you gotta fck around w em for a while. pick 4 for each catergory n change to another one every 3 weeks. keep detailed log book so you can see whats working for you or not. record your lifts n crap. this is an advanced lifting regimine but works awesome.
before using an exercise for ME day, make sure youve used it as a secondary exercise for at least 3-4 weeks
theres no need for OHP, your shoulder gonna get pounded benching 2x a week. lateral / rear raises are all you need. keep in mind this is PLing not BBing. theres a body building template out there too but its way different if that interests you more
