I've been rotating 8 exercises for my upper and lower body days, but I was wondering if there are any negatives with just rotating bench press and press on upper body days and back squats and Deadlifts on lower body days? I was thinking about just doing this for 8 weeks to see if it works or if I stall. The only reason I want to try this is because I really like doing those lifts the most and I read somewhere that for raw lifters, it is better to keep the rotations down to a few exercises.

Thanks in advance for your help.
