I seem to be the only person in my work gym who even bothers with deadlifts, not to mention squats. Anyways when doing stiff legged deadlifts I'm not really feeling anything in my quads. (isn't that whats supposed to be worked) My lower back though is certainly feeling it. I do bend my knees and stick my head forward but my lower back is always sore after my sets. Is this right or is there something wrong in my form? I'm still fairly new to lifting, my highest weight is 160 pounds.
