This is really going to depend on your structure. what if you work the hell out of deadlifts, and it stays one of your weaker exercises. Not for lack of effort but lets say your body structure just doesnt work well with them. then lets say you do a bent over BB row, and that goes from 135 x 10 to 405 x 10. id bet those BB rows gave you one big ass back. point being IMO its the ability to progress in weight on a lift that counts, not the lift itself. Well to a certain degree anyway. and no im not talking about 1RM here im talking about moving an assload of weight for a lot of reps. like dante said turn yourself into a human forklift.
