When I started deadlifting a year ago I was doin 135 for reps. This year I was doing 225 fo reps. Up until about a month ago when I changed form. I now reset and think about my grip and starting position really quick every rep, and Im now working out with 315 to 325 for about 5. The thing is I dont use starps or a belt. My grip is having a hard time getting the last few reps. I also use an over hand grip with both hands. I just cant switch that yet. My roomate says I could do more if I do...What do you guys think ???
