Hey guys i want to change my split routine because when i do chest and triceps i have trouble lifting heavier weights when i get to triceps idk why....and when I used to do biceps and triceps i can do them much better and with alot more weight than when i do my tricep workout with chest workout. Does anyone have any suggestions as to what should I do this is my current plan:
Monday- Legs
Tuesday-chest , triceps
Wednesday- Off
Thursday-shoulder traps
Friday-back biceps
Weekends-off
*Every once a month I do drop sets*
Monday
Legs-(Leg curls 3 sets of 8)
(Back leg extensions 3 sets of 8)
(Squats 3 sets of 8)
Tuesday
Chest-(Bench press 3sets of 8)
(Incline Bench 3 sets of 8)
(Push ups 3 sets of 15)
Triceps-(Skull crushers 3 sets of 8)
(Kick backs 3 sets of 8)
(Body weight Dips 3 sets of 15)
Wednesday -----Off
Thursday
Shoulder-(Up right rows 3 sets of 8)
(Military press 3 sets of 8)
(Standing Dumbbell rasies 3 sets of 8)
Traps-(Shrugs 3 sets of 8)
Friday
Back (Back military press for back 3 sets of 8)
(T-bar rows 3 sets of 8)
(Bent over rows 3 sets of 8)
Biceps (21's)
(Biceps Curls against Wall 3 sets of 12)
(Hammer curls 3 sets of 8)
It's not my complete workout plan(sorry short on time). What I what to change is to put biceps & triceps together because that seems to work better for me.

However, should I put chest and back together or what do you guys think
