Pulling near your maximum capabilities more than every 10-14 days can be HARD on your body.
I can often pull 2x a week but only for a couple of weeks. One day will be VERY intense and the other will be with a maximum of 65% of my 1RM and I hardly ever pull for more than singles. If you want to build the deadlift, build it by committee. Good mornings, box squats, reverse hypers, glute ham raises, manual leg curls, upper back work, etc...
