a quick simple work out routine, is this okay?

[Injured1]

Hi, I am new to the boards, so please bare with me. I was wondering if you guys can help me out. I use to be in the gym alot 4-5 days a week. I use to do Isolation workouts, and got results. Then I switched to compounds like deadlifts, squats, rows, clean and jerks, close grip presses,ect,ect. It seemed I got better results with those, not per particular muscle, but overall body mass. Anway, I have been out of the gym for over 2 years. I have had 3 concussions, abb tear( which needed surgery ), and other injuries. Also, I have now been busy( outta highschool now ) with college and now an up coming EKG program. So basically I don't have too much time to lift. Point Blank, I need a workout routine that I can do in 1 or 2 days that will hit my upper body( Primarily my Biceps, Triceps, and chest..in that order ). I have thought of a couple workouts, but I don't know because I have never worked out in just 1-2 days. So, here they are:

1 Day workout
Chest press( done vertically )3x8
Dips 3x8
Tricep pull downs 3x8
Machine Rows 3x8
Pull ups
Bicep curls

- I don't know if that seems too much for a day, but considering it's only 1 day a week, i don't know if that's overtraining, of it just seems disorganized.

1 Day workout( less version )
Chest press( or sub with dips )
Pulldowns
Machine rows( or pull ups )
Bicep curls ( or hammers )

or Two day workout:

Day 1
Chest press
Dips
Tri pulldowns

Day 2
Machine Rows
Pull ups
Biceps curls


So, bascially that is it. What do you think? Or heck maybe you have something better for me to do. I am all ears for this. If you want tweak my workout, either one of them, that's fine. My goals are not to be the most massive person, I realize, not possible. I use to bench 275 free weights( I don't even know what that would be now ), I don't even need that goal. I am just looking for a 1, maybe 2 day work out that will hit my upper body and add a little mass. Maybe half an inch to arms in 8-10 months, and a little bit more to chest. So, what do you think???? Again, I am new to the boards and out of the loop of lifting for awhile, so bare with this post. I appreciate coming to people who know how to help. Thanks
