Back Workout Routine for Mass

I have been doing this back routine for a few weeks now. It is very basic, and doesn't take too long to complete. Feel free to add sets, or additional exercises, but this is what I typically do:

• Deadlifts: pyramid up in weight: sets of 10, 5-6, 3-4, 2-3, then deload and a set of 5.
• Weighted Wide Grip Pullups: 4 sets of 10 reps (if you can't get all ten with the weight, dump it off and do weightless to get your 10 reps)
• One Arm Rows: 3-4 sets of 6-8 reps (go heavy and don't worry so much about form)
• Shrugs: 4 sets of 10

Done.
