Have been working out for 4 Months now

4-5 meals containing:
3 meals = 2 x chicken, mixed veggies, kidney beans, peas
other 2 might be Oatmeal or some Peanut Butter, corn flakes, etc.
No supps not even protein powder yet

i started off on the wrong foot
later focused on compunds more
have been following the following routine for the past month now
which i got as suggestion over another forum:

Workout A
Squats
Bench press
Bent-over rows
Military press
DB curls
Hanging leg raises

Workout B
Deadlift
Chinups
Chest dips
DB rows
Skullcrushers
Calf raises
*Alternating between A and B every week

problem: arms isn't developing at all. that's primary concern atm. i guess it has sth to do with diet or training. help is much appreciated.
