I'm doing
back/tri
chest/bi
shoulder/legs
I do a 10-8-6-15 rep range (vince gironda technique)
and i have 2 full body power days
I have a part A routine which consits of supersets and part B which consists of tri sets, mainly volume training, doesn't matter what body parts you work together or what you do, I'm pretty sure some top bodybuilders have used the split you want to do, it's all about technique and nutrition,just gotta find what works best for you
