The two leg days should work well for bringing them up to par. If your shoulders are your other main concern why don’t you : 1. replace one of the triceps movements on Monday with a shoulder movement. 2. do your db shoulder presses first on Thursday, and use a barbell.
Have to agree with Energy. I’ve always had a tough time piling the muscle on in my legs - therefore I always do them first in a workout cycle, when my energy is up and I’m thoroughly rested.
I like how you arranged your Tuesday/leg workout. Wow - how is that going?
