Starr has it nailed. Hell all this bull about needing to do exercise after exercise is just trash. Even the bodybuilders that started doing splits pre contest back in the day thought they were helping with cuts and definition which is bull as well.
As the loads become heavier you need to wise up and train smarter. This might involve splitting your training more, but that shouldn't mean adding in every exercise known to man. Adding in addition exercises with no purpose is idiotic.
