Can't get quotes to work, anyways..
For Chest, I'll definitely add in the PJR's, also considering adding in close grip bench as well. Somewhat worried there might be too much interference between the two muscle groups though, would I be better off just swapping Bi's and Tri's perhaps? (no, there really was no reason in particular to split the bi's and back together)
For Legs, I was kinda worried about this too, I originally had DLs on back day, probably will move them back to that day.
With the back, see Chest & Tri's above. Also was probably going to add shrugs since it seems most of the exercises are hitting the lower traps.
And for shoulders, I'll add in Lateral Raises and Face pulls and cut the front raises. Any other Delt exercises you'd recommend on top of this? Rear delts seem tricky to hit.
After looking at it, I really wouldn't mind just adding another day to further split it. Bi's and Tri's would seem like a good combo to move to a separate day, but I feel kinda silly having a day strictly devoted to arms. Perhaps its that negative vibe I've gotten from watching kids spend 2 hours curling, but whatever, I digress... Is there anything wrong with just having an Arm day?
