oh dear...i kinda feel sorry for you. cos if any of the others guys join in you myt get taken down...but i'm feeling gd atm so i'm going to tryand help.
okay lets get started. firsty....can you get to the gym more than 3 times a week. I say this because at the moment i'm doing an upper/lower (DC) split. i'm training 5-6 times a week, rotating 3 workouts for each and my strength is going up the quickest it has ever done.
Since you are a beginner you can train more often as the weights you are using aren't causing that much damage/fatigue.
I don't understand why people always regiment their workout plan so exact with every exercise they're going to do planned out, just makes things complicated. What are you going to do when your legs are all DOMS from the 1st week of back to back Squats, RDLs, Squats?
this is good but personally I would do Main-assistance-isolation for all muscles group instead of going from a muscle to another. and I would cut some chest volume
like instead of workout A
Squats 5x5 chest DB press 4*8 (maybe you should go heavier, like 5x5 with a Barbell) Lunges 4x8 Close grip barbell press 3x8 DB Skull crushers 3x8 chest flys 3x10 Calf raises 4x10-12 (if you are sitting go heavier)
I can tell you he won't be getting DOMS after the first week if he follows a routine of that frequency. The only time I (or anyone I know) gets DOMS is when a new exercise is tried, or when doing an exercise less than twice a week/three times every 2 weeks, such as in a typical BB split.
Also if you don't plan out your exercises then how do you ensure constant progression? There's a lot of hate around this site for proper programming, as if somehow it doesn't make a difference. I can understand planning to do 5*5 on back squats and then picking accessory work based on how you feel, I don't understand how someone can go to the gym and think "I may do squats today"
EDIT: Just want to be clear that I don't think the routine posted is "good". I think someone mentioned an upper/lower split, which is probably the way to go, with a focus on a few key exercises.
