5 Most Effective Back Building Exercises
 

Deadlifts. Nothing builds beefy backs like the deadlift. The sheer act of holding a barbell with heavy weight places the lats under an incredible amount of stress.
Pull Ups. A far superior choice to lat pull downs. If you can do one, try for two. If you can do two, try for three! If you can't do them at all use rack chins.
Barbell Row. No back building workout should be without a heavy row, and barbell rows are at the top of the list.
Dumbbell Row. An excellent second choice to barbell rows, especially if you have a weak lower back.
Power Clean. The explosiveness of the power clean effectively works the back from traps down.
