Relvant info: Male, age 26, height 5'10(180cm), weight 160lb, no long term injuries or illnesses
Goal: Muscle hypertrophy and modest strength gain
Plan for progression: Adding more sets, swapping exercises, changing reps, deloading
I started lifting again from a several month hiatus and I started with a 3 day full body split.
My working sets ended up looking like this by the end of this first mesocycle(Wed, Fri, Sun)
Squat 3x12
Bench 3x12
Lat pulldown 3x12
tricep pressdown 3x12
Bicep cable curl 3x12
calf raises/shrug superset 3x12
forearm ez bar curls 3x15
glute ham curl 3x10(somtimes)

After 3 months and some decent progress I switched to a 4 day upper/lower split for shorter workouts and more scalability.
The upper days on the left and lower days on the right(Tue, Wed, Fri, Sat)
Flat BB Bench 3x8 BB Squat 3x8
Incline BB Bench3x12 Leg ext. 3x12
Lat pulldown 3x8 Glute ham curl 3x12(emphasis on glute with form)
Seated row 3x12 Leg curl3x12
Shrugs 3x12 Calf raises 3x12
3-way raise 3x12 Forearm ez bar curls 4x15

For each upper day I will swap the back and chest exercises to maintain a balance as well as Squat with Leg press. This is everything. The upper/lower split is still primarily for hypertrophy but the reps on the first exercises of the main muscle groups is lowered to work on strength.
My questions for anyone who wants to help
Do you think this seems like a decent progression(i.e. not too much and not too little), Do my workouts make sense to you, When should I begin adding more sets or exercises, and finally where do you think my plan may be lacking and what would you change about it for you personally.
To anyone who read through this I appreciate your time and also thank you to anyone who comments.
