Gee, I could have sworn I wrote the words "rows" in there as well.
Just a hint, but you may want to see who has pics up before taking advice. If they have no back, quit listening to them.
Your middle and upper traps are activating with any rowing movement that would involve the angle from when your arms are straight in front of you to when they are down in a shrug position.
Hammer Strength makes great back equipment. They helped my back get bigger than most of the people who seem to be on the "rack pull" bandwagon all of a sudden.
Heavy shrugs and rows work. Deadlifts are a great exercise for some people also. Why do we need to rewrite that?
