@joann100 i would try heavy in the penultimate set which would be 3rd for you. Also i feel 4 exercises for isolation exercises could be little too much. 3 is a good set number
@joann100 I like your exercises selection. I'd suggest doing PPL and then upper lower. Mix Back and chest on upper day.
I think if you do repeat this in the same week it could be too much volume especially for upper body.
