Try the Barbell Bent-over Row as I find this is a great exercise for back development.

How to perform

1. Grab the bar with palms facing down about shoulder width apart.
2. Bend your knees and lean forward bending at the hips and have your back straight.
3. Try to bend down just about parallel to the floor and keep your head up.
4. Hang the bar straight down in front of you.
5. As you exhale out pull the bar up towards you. At the top hold for 1 second and squeeze your back muscle.
6. Slowly lower the barbell back to the start position while you breathe out.
   Repeat movement for the required amount of reps. I would start with a lighter weight than you can normally lift and do 3 to 4 sets of 8 to 12 reps.
