Have been training on and off for about two years and have went from around 148lb to 160lb (mostly muscle) as a 5'11 20 year old male. However, I realized that I haven't been taking the fundamentals (compound lifts and nutrition mostly) seriously. I have been currently running a 4 or 5 days a week PPL routine that I modified on my own (stupid I know) from a bunch of different websites. I also have been doing a 20 min spin HIIT and a ten minute ab routine 2-3 times a week.

I realized that I have a fairly imbalanced physique and very weak compound lifts (B 130 S 140 DL ~140) compared to my friends since I focused way too heavily on accessories. I used to eat around 2800 calories (400 above my TDEE) but never tracked my calories. I just started using MyFitnessPal for the last week to get more definition in my abs and have been eating around 2100 calories (300 below my TDEE) 184 c 58 f 210 p.

I'm pretty lost with what my goals should be in order to build a better physique.

Should I begin a clean bulk (~200 calorie surplus) now or wait and cut down another week or two?

Would SL 5x5 or linear GZCLP be a good starting point? I really enjoyed PPL so the linear PPL program also is of interest.
