My upper back feels tight, but you are right it is not tight enough. I have really started working on my hip and shoulder flexibility. I found some stuff on the site about broomstick stretching. I think that once I get my shoulders more flexible then I will be able to bring my hands in a lot more and have a tigher upper back.
I noticed that I need to push my knees out more and your comments confirm this. I will practice "spreading the floor" during my squat workout today.
I really do appreciate the comments. I am trying to perfect my form on the basic barbell compound movements because from what I have seen the biggest and strongest do it. Makes sense to me to see what successful people have done and emulate it to a certain degree.
