Ok, on ME day how I like to work up to a 1RM is like this, i do easy weight, 3 sets of 5 reps, then move to 3 reps then 1 rep until i hit a 1 rep max.. example would be.. what i did for deadlifting
45 x 5
135 x 5
205 x 5
255 x 3
285 x 3
325 x 3
360 x 1
365 - miss
Now remember, i was planning on like a 400lb pull so thats why i went for 325 x 3. Usually it takes 3 singles for me to reach my 1RM. I try to make it so that my last set of 3 reps is kinda of hard, but i could put up 4-5 if i wanted to.
