Upper body strength/circuit training suggestions

Spanntastic12

Currently I'm working out at the gym that I have in my apartment and doing 4 to 5 different lifts two nights a week.

The staples of which are:

Machine Bench press
Seated bicep curls (dumbbells)
One Arm bent rows
Machine Fly
Push-ups
Overhead press (machine)

I'll add lat pulls at times. But are there any exercises that you guys can suggest to add to the list? I appreciate the input.
