Exactly, a lot of people don't listen to that advice. If it hurts or don't feel right STOP FRICKEN DOING IT!!! Doing it because someone else does or can even though it hurts doesn't make sense. A lot of people will continue wrecking themselves because so and so told them to. I don't care if a lift puts on 20# of mass a week if it hurts I don't do it. After the army I dont move like I use to and I can't do dead lifts anymore without pain, so I don't do it.
