i weigh around 174-178 and i pulled 400lbs today just to see if i can do it. now im gunning for 500lbs. my deadlift rep range is usually 4-6 max-ot style with weights averaging at 330-365lbs. at what weight percentage of my max should i work with? 400lbs was just my 'ill do this and im happy for today' weight. thanks and i got my supps from 1fast with a free shirt, in medium ofcourse cause im light weight.
