is it possible for me to progress to a 661 deadlift, 300kg, in about 2-2.5 months? my best pull was 617 (280kg) about 3 months ago,and since then i haven't PR'd, but i have pulled high reps consistently, all from a dead stop. My best set for reps was 515 for 7 reps from a 1 inch deficit. Is there a way for me to use bands or maybe tap and go to overload the top portion? i usually do my accessories next day, but usually they are heavy barbell rows, pull-ups, a machine row variation, and weighted or banded hyperextensions. i haven't failed in the last year but when i do fail, its usually right below the knee. Would i benefit from doing GHR's(i can't actually do a full one, but assisted or even just the ham work) or RDL's just for the ham work? good mornings don't really do a whole lot for me.
