I did not read through your entire workout but I noticed one big mistake immediately....you are working Biceps on Monday and then working them again on Tuesday when you train Back.

You are also using your triceps for 3 consecutive days.

i agree work back and bi's together and chest and tris.You are definately overtraining, you need to give your muscles rest so they can grow. This is my routine.

Monday chest and tris
tuesday back and bis
wednesday off
thursday legs
friday shoulders and traps
saturday off
sunday off

I recently switched legs and shoulders/traps around because I need that extra day for my shoulders to recover from chest day.

I do a similar 4 day routine and it works great for me. You might consider re-ordering yours, so certain muscle groups get enough rest.

Day 1 – Chest, Biceps, and Abs
Day 2 – Legs (includes calves)
Day 3 – Shoulders, Triceps, and Abs
Day 4 – Back and Calves
Day 5 - Rest
Repeat cycle
