any help would be sweet

Looks like a little too much and kind of unbalanced, but gie it a try and see what happens, if u r getting stronger it is fine, if not, change it.

1. Add a day off between chest/back and legs

Day1: Chest/Back
Day2: Off
Day3: Legs
Day4: Weapons of Mass Destruction
Day5: Off
Day6: Repeat

2. On chest/back day, swap out pullovers for DB rows or chest supported rows.

3. Drop one of the fly movements. If you're concerned about not hitting that angle, do incline or decline close grip bench on your arm day. As it is, you have too much pressing and not enough pulling.

4. Swap out leg extensions for a squat or lunge variation.
