Here is a routine used by a lot of people in my gym. Among those a guy who deadlifts 355kg (790 lbs) clean.
The routine is based on training twice a week and in the example your 1RM is 100 lbs, just to make it easy to read.
(Reps/sets/lbs)
Week 1-1: 5/3/70
Week 1-2: 1/1/75-2/1/75-1/1/75-2/1/75
Week 2-1: 5/4/70
Week 2-2: 1/1/80-2/1/80-1/1/80-2/1/80
Week 3-1: 5/5/70
Week 3-2: 2/1/80-3/1/80-2/1/80-3/1/80
Week 4-1: 5/3/75
Week 4-2: 1/1/85-2/1/85-1/1/85-2/1/85
Week 5-1: 5/4/75
Week 5-2: 2/1/85-3/1/85-2/1/85-3/1/85
Week 6-1: 5/5/75
Week 6-2: 2/1/90-3/1/90-2/1/90-3/1/90
After week 6 you need to take a break for about one week and then in week 8 you set a new 1RP and ajust the weights in the routine accordingly and start over again.
