I'm a beginner with free weights at my home. I'm not looking to become huge, just slightly bigger. I wont say a weight because I can't guess.

But here's my routine for my upperbody:

I do 2 sets. When I get to 8 Reps of a particular weight I increase the weight. I leave one minute between the first and 2nd set, I rarely get as many out in my 2nd set, it's more for endurance I guess.

Tricep Extensions
Bicep Curls
Hammer Curls
Close grip Chest press
Shoulder Press
Behind Head Shoulder Press (I don't know it's actual name)
Bent Over Rows
Upward Rows
Chest Press Wide Grip
Lateral Raises
1 Arm Bent Row
1 Arm Shrugs
Overhead Rows

I'm wondering if this is ok or do I need more exercises for different body parts? I'm thinking about dropping the "Behind the Head Shoulder Press" and the "Deadlifts" because I keep hurting my shoulder and my back from poor technique. I'm strapped for time, it takes approx. 2 hours for that routine.

I do that 3-4 times a week depending on how I feel. (I normally take a 2 day break over the weeked). Do I need a larger break?

Thanks for any help you guys and gals can give me.
