I feel like you're doing too many exercises and not putting enough effort on the big important ones as a result.
Have you tried just bringing it down to 2 workouts with 3 or 4 barbell movements for each workout (for a total of 6 to 8 exercises)?
I'm a fan of:
- Barbell bench press
- Overhead press
- Dips (weighted or assisted as necessary)
- Pull ups (weighted or assisted as necessary)
- Barbell row
- Squat
- Deadlift
You can get through these and train each to failure on only about 2-3 hours per week of training, maybe across 2-3 days.
I'm in my 40's, so it takes a lot of warming up to get up to work sets of more than 3 plates on squat and more than 4 plates on deadlift, but even then I'm maybe in the gym only 2 hours per week on strength work (and doing cardio/conditioning another 2-3 hours per week).
If you're not seeing progress, it might be because you're wearing yourself out on the accessory lifts that don't actually do much until you're already really strong.
