Okay my dude I'm going to chime in I'll apologize I didn't reply earlier...
What is very pivotal is you cannot overtrain but you have to understand that at your level it's not about a nihilation but rather stimulation.. normally I would suggest people do them 2 times a week but I'm reviewing everything you're saying and I'm going to explain to you why it's not going to be necessary 2 times a week but we'll get there in a minute.
You will train your bi/tri's on the same day, you can make it a Monday..
Straight bar curl wide grip 3 x 12-14 (don't exactly count the wraps but lift until failure but definitely try 2 rounded about that you're failing at 12, if you can blast out to more good for you but do not cheat.
E-z bar 4 x 10-12 regular grip
Standing alternate dumbbell curls 4 x 10-12
Seated incline dumbbell curls, do not alternate and do them simultaneously, with elbows and but you're dumbbell somewhat out simulating a wider grip, extend all the way down to wear your arm is fully extended and then curl up again, do these repeatedly without a break or hesitation.
Machine preacher curls 3 x 10 - 12
Overhead cable curls 3 x 10 - 12 (make sure the upper cable pulley is level with your shoulders)
Lower cable rope curls 3 x until failure (High Reps for a pump and burnout)
Tri's
V bar 4 x 12-14
Rope pull down 4 x 12 - 14 (look out at the bottom and squeeze, return to the top slowly and the instant you hit the top immediately bring back down hold and squeeze)
Reverse grip shoulder width upper cable tricep extension pulldown 4 x until failure (High Reps greater than 12)
Overhead dumbbell extension 4 x 12-14
Seated dip machine 4 x until failure ( back straight, and chin up look up if you can, do not lean forward or look down)
What you could also do is incorporate 2 bicep movements on back day, after you have exhausted your back routine, I would suggest lower cable bar curl 3 x until failure (hi rap just for blood pump) and EZ bar regular 3 x until failure)
Arm chest day after you have exhausted your chest routine I would suggest incorporating close-grip Smith machine press, 4 x until failure greater than 14 reps.
V bar tricep extension pulldown 4 - until failure greater than 14 reps..
