Following JP for a while now and he preaches upper/lower(maybe not for the REALLY TOP open strong AF guys). His thought proces is you hit everything at least twice a week(Upper, lower rest repeat for example). That means you stimulate a muscle 2/3 times per week instead of just 1(brosplit for example).
For the really big strong open bodybuilders this maybe would dig an recovery hole(even though JP does upper/lower from time to time, and he says he literally sees double the growth from it when he does and can handle it). Of course AAS/GH and stuff does something for protein synthesis, but it also let´s you recover more quick. It seems to be normal/the trend to do brosplits(or PPL) those days because (most) of the really TOP dogs do it, but should we?
*And of course you should train the way you enjoy it yadayada but just some food for thought.
