Mate you need to dramaticaly shorten your workout. You can either train hard or long, you can't do both. You need too be out of the weight training area in under an hour. You are doing a push/push and pull/pull system. It's ok but not ideal. You could very well be over stimulating your bi's and tri's bro. A common misconception is that those smaller uscle groups need the same amound of work as the larger ones. This is not the case. Your arms are under tension while you train every other body part. It is very easy to not gain or get little gains from a work out schedule like that. I would change to chest and bi's back on its own and shoulders and tri's. It is a personal thing as well. God luck bro. If you want more help PM me and I can outline more stuff for you

Where is your Core/Abs? Your core stabilizes all exercises. I would shift the days around also Tues/Sat rest, and spread the Bi's/back and shoulders/Traps out another day or so they are auxiliaries to each other, give them rest before you work them again.
