A lot of it depends on goals. Shitzo obviously who is defunct and no longer posting - he needs a total makeover. He needs a 6-12 month boot camp due to his disastrous shape.
Guys like Goodrum - its more diet and adding in some compounds and functional fitness as well as cardio.
Young dudes, sure, do the old bro splits for hypertrophy. It definately works for young guys who want to put on muscle.
This is not rocket science, its common sense and a little discipline.
