Another deadlift question
As many of you know, i suffered a back injury last year. I am trying to get back in the gym and I have started to deadlift again. I have been in a squat rack with the safety bar slightly below my knees. I know I'm getting some benefit from this. My question is. Should I be trying to go all the way down to the floor with my lifts or will the 3/4 lift help me enough to build my lower back muscles?
