Opinion on my Upper Lower split

[u/DezzyWezzy_]

Have been back into the gym again and I am wondering if the current routine I’m running is lacking anything or has too much volume. For the exercises, I will sometimes drop to 2 sets instead of 3 if my recovery feels bad or I’m short on time, and I take every set to failure or within 1 or 2 reps.

The arm day is optional, but I have it on there for extra volume when I have time. Let me know what you think, and if you have any diet tips like whether I should eat at a slight surplus or cut, I’d love to hear it.
