Just my humble opinion, but I always felt like PPL is trying to cram way too much into each day. I mean your pull day has 9 different exercises. I’m also in my mid thirties, so if I did 2 hours in the gym my joints would probably shit out on me. I feel like the sweet spot is a warm up and 6 exercises.
I like doing a push-pull-legs-shoulders/misc: chest, tris, abs
Back, bis, forearms
Legs
Delts, traps, lower back
Maybe you’re overthinking? Once you get started and have it as a habit again you can keep tweaking your splits. Obsessing over things now isn’t going to do you much good. I always tell people that the important thing is building a sustainable habit.
If you are just getting back into it, going to the gym and doing 4 exercises on different machines is a successful day. If you come in and completely overdo it you won’t want to come back the next day. Not to mention if you don’t have a baseline strength you are very likely to relax your form and injure yourself. Once you adjust you can keep adding and adjusting things until you get a split that you like.
Honestly, it feels like you are trying to jump ahead. Don’t be so hard on yourself.
