I find the dead lift thing interesting. I did my team challenge yesterday, dead lifting 170lb over 100 times, and today the only thing thats really sore are my lumbar spinae. My upper back is a little sore, but that's because I did pull ups and rows after that. The dead lifts seemed to hit nothing excpet my lower back, so I always wonder when people talk about deads hitting the whole back.
It just doesn't work that way for me.
