Hey, I tried looking at a bunch of splits and just combining what I liked but I’m not sure it’s any good. Any feedback? For context, I’m just working out for fun and trying to bulk from 175 to 190.
That's not "working out for fun" :-)
I mean, those are going to be long, hard workouts with progressive overload. And if you intend to gain 15 pounds ofc you want most of that to be muscle. The good news is UL is a great choice and you're hitting all the major groups, with compounds first and isolation last. If you find recovery to be challenging, there is some overlap there, e.g. leg press after trap deadlift. I'm not saying don't do the leg press, but you might consider higher reps and one set less.
Why do you have upper A and B with:
Row 3x8-10 at 135
Row 3x6-8 at 130
If your goal is lower intensity on the second workout then why not drop the weight about 20% and do more reps like 12-15?
If you're just starting out, I'd say this is way too much volume to start with. Remember the goal is progressive overload. Beginners don't need to start out at 100mph. If you're new, do just one exercise for each group each day, e.g. chest, back, or at least drop one or two sets total, and as the weeks progress add in a set or an exercise to get to this list.
There's a lot to like about how you put this together…
Every body part worked 2-3 times per week…check! 10-15 sets per week for major muscle groups…check! Rest days integrated to allow recovery…check! Heaviest moves at start of workout…check! Compound moves before isolation work…check! Hitting muscles with different angles, rep ranges…check!
Only a couple minor improvements I can think of…
Your chest works up to as heavy as 4-5 reps, but the rows don't go heavier than 6-8, and the chest has 13 sets in the week to the back's 12. (Lower back raises are not counted here.) Over time, this will cause a muscular imbalance where the chest gets stronger than the back, pulling the shoulders out of alignment, limiting range of motion at best, causing lots of pain at worst. You should consider adding an extra set for the rows each day (it's ok to have more back sets than chest), and have your Thursday rows be sets of 4-5 reps to match the heavy bench on Monday. Balance is the key.
The other item: posting your workout in the exercise section of the forums will draw more attention than in the getting started section.
Otherwise, welcome @Gyuuk ! Welcome to the forums, welcome to the brotherhood of iron, welcome!
