I've done this back routine before, and it really did put some nice growth onto my back, faster then any other routine that I used. The only other routine that came close was a two hour routine, 5 days a week. The muscle groups were broken up the same way, but I would do a hour of overall workout, then a hour of isolation based training to the muscle group of that day. And really, when I see a lot of the guys at the gym and what they do, these workouts are not much. I only workout two muscle groups a day, generally.

And I give a large focus to the back, shoulders, stomach and chest. A lot of guys at the gym do far more then this, so I don't think it is over exerting or anything like that. And yes, I am very tall. Anyone have any advice or critique for me?
