A post by me from another thread:
Well, I think some lifts suit certain individuals better than others. For instance, squats are a great exercise but there are some (such as myself) who always have difficulty nailing the technique and therefore, didn't benefit from the lift as much as others did.
What you said about deadlifts in regards to physique could be said about any lift imo.
However, if a guy can deadlift big numbers, he usually has strong overall muscle density and impressive athletic ability. Pretty much every top strength athlete will be judged on their deadlift, more so than on any other lift. There are many WSM competitors with average (in context) bench numbers, but there isn't one with a poor pull.
