There are lots of different training methods and I won't make a blanket statement and say that one is better than another because everyone is different. I will say however that I do not see how in the world any of you guys are training any other muscle on the same ay as back. When I'm done with back, my whole body is tired, same as with legs. Those muscles are so big they fatigue my whole body so I do them on seperate days by themselves. Its my opinion that if your doing any other muscle on the same day as back, then your not hitting back hard enough.
