Alright, I got it. So should I do this workout

(Workout A

Bench Press
barbell curl 3x8

Workout B
Squats
Overhead Press
chin-ups 3x6-8

Workout A
Deadlifts
Bench Press
calf raises 3x12-15)

as long as I progress? Some of my friends told me that I shouldn't do same workout for more than 5months? What do you suggest?
