Only goal is aesthetics, any reason to work under 8 reps?(1 year experience)

[cjc651]

Right now I do a 5 day lifting routine like this:

Monday(Chest & Tri's) Bench press 5x5 (followed by progressively increasing reps on other exercises for hypertrophy)
Tuesday(Back & Bi's): Deadlift 5x5 (followed by progressively increasing reps on other exercises for hypertrophy)
Wednesday(Shoulders & Traps): BB shoulder press 5x5 (followed by progressively increasing reps on other exercises for hypertrophy)
Thursday(Legs): Squat 5x5 (followed by progressively increasing reps on other exercises for hypertrophy)
Friday: Arms and abs (strictly hypertrophy rep ranges 8-12)

So obviously I have a 5x5 compound lift for each muscle group. I continue to make strength and size gains each week but I'm just wondering if it would be better for me to do something like 4x8 on my compounds if my only goal is to get bigger.

Thanks

It's always going to be beneficial to build the best strength base possible using low(er) reps before thinking about training for size. But you could also utilise both rep ranges, ie. week 1 use 3x5 or 5x5 for strength, then week 2 use something like 3x8 for size, and just alternate between.

under 8 reps is better for tearing muscle fibers... so yes, otherwise you're cheating yourself out of half of the gainzzz equation.
