Can anyone give me some helpful tips on how to perform the conventional deadlift? I've been doing them and up until this monday I thought I was doing them right but some powerlifter said I wasnt using any leg drive. He said I was kinda stiff legging it. I've been trying to practice on my form but Im not sure if Im doing it right as my lower back seems to really get soo pumped that I cant even walk. I keep my chest out, head up, and I try to not jerk the bar up. I will try to get a video up of me deadlifting.
