i would also like him to touch base on this.
bench
I did full body routines a few times.
I think they're possibly the best routine you can follow as a beginner, and especially as a natural beginner.
When you first begin training with weights, you don't have the neuromuscular pathways to properly isolate each muscle. Much of your initial progress in strength is actually proliferation and improving this. Since you don't have the ability to properly overload the working muscle, attempting to isolate a particular muscle is pretty much useless.
By doing full body routines, you'll take advantage of your decreased ability to damage each particular muscle by hitting each muscle multiple times a week.
This will also speed up the neuromuscular adaptations to training.
As you become more efficient at these processes, you'll begin getting more sore and taxing each muscle group more fully. At this point, you may want to go to an upper body/lower body split.
Eventually (if hypertrophy is your goal), you can move to a single body part per day routine.
I still do multi-body part routines when training for powerlifting. Yesterday I did Bench, Dips, Seated Military, Laterals/rear lateral, Pull ups, One arm rows, and finished with tricep extensions. Just a few sets of each.
