need some help with my routine! (4 day splits... hit me wid em!)

[Tha Don]

my 3 day...

chest/bi - back/tri - shoulders/legs

...routine ain't doing much for me

basically from 2 weeks ago i've put on fat and lost LBM?!?!?! its weird i'm really ripping my muscles but they ain't growing right (and yes i'm on 3500 cals and 40g of protein per meal) however i am getting stronger! its weird, i really can't build mass with this, might work for some but not for me! and my goal is mass not strength

i'm thinking of changing to a 4-day split

my aim over the next few months is to add a lot of size to my upper body - i got told yesterday by a guy at the gym 'you need to bench press', he said my arms were decent, but i lack a good chest and a set of traps - so these parts need priority, i don't care too much about size on my legs... although i don't want to neglect them totally

someone told me... chest/back - shoulders/arms - legs ...worked better for him than my 3 day split, so it could be someting simple like switching bout the muscles i'm working

i'm thinking of...

chest - back - rest - shoulders/legs - arms - hiit - rest

...if that really don't work then i'm going back to my old...

chest/back - rest - shoulders/arms/legs - rest (day on/day off) routine ...that worked okay for me (well better than my 3-day split, but it was a lot to cram in!)

please suggest something that might work for me considering the information above

p.s. i'm tall ectomorph, been training for 3 years, 19 yrs, 178lbs 10.4 BF

peace

think i'ma go with...

d1-chest
d2-back
d3-shoulders/legs
d4-arms

(similar to the one you suggested P-Funk, but my legs don't take that long, i really don't need a whole session for them *yet*, as soon as i can squat propery and they start to develop a bit more i give them their own session)

then once i want to add legs i'll look at this...

Chest
Back/tris
shoulders/bis
Legs

(I prefer to have fresh arms to work on, rather than half knackered arms, although i have not tried bi or tri after a lift that incorporates it so i might have to try it first, could work better for me, could not...)

if non of the above work i'ma do this one...

Mon ??? Chest/Back or Shoulders/Arms + Abs
Tue ??? Rest
Wed ??? Chest/Back or Shoulders/Arms + Legs
Thur ??? Rest
Fri ??? Chest/Back or Shoulders/Arms + Abs
Sat ??? HIIT or Legs
Sun ??? Rest

in the past i've always felt working my body twice a week works, i used to go every other day and do either the chest/back or shoulders/arms and i know when i missed out a day i would struggle, it just worked really good for me
