Ive been doing PPL for two months. My weak points are hands (biceps mostly)

 

I would like to add a bicep excercises to a leg day or have a additional day straight after legs day purely for hands.

Which would be most beneficial?
1) add bicep to legs day
2) add additional day straight after legs for biceps
3) add addtional day straight after legs for bicep+tricep
4) no need additional for muscle growth, just kill it on your PP days

Sorry I did not mention I am doing 3-4 days per week (every other day off). I will add bicep to my legs day and see how I go. As I understand, since I have plenty days off during week (also just finished my recovery week) then no big deal that I add extra workout day if legs+bicep will not work.

I see. You're totally right, if you basically have 3-4 workouts per week, adding in another day where you hit more biceps isn't going to be bad at all. You could simply make it a weak point day if you wanted to do more than biceps. Besides, if you leave it JUST as biceps on their own, it won't be hugely taxing anyway, so definitely no harm in that.

Then I might even add Chest(upper) on that day.

 

Could you give me advice of below split?

Day 1: Chest + tri + shoulders + abs + HIIT
Day 2: back + bi + abs
Day 3: rest
Day 4 (weak point day): Chest + bi + HIIT or moderate cardio
Day 5: Rest
Day 6: Legs + abs
Day 7. Rest

 

OR

Day 1: Chest + tri + shoulders + abs + HIIT
Day 2: back + bi + abs
Day 3: rest
