I am still learning too, but one thing I've done is for the past three sessions, I have used the cage and set the pins at the very very lowest level possible....not a rack deads, but about 6 inches off the floor...maybe a quarter plate.....my weight has been increasing weekly, I DO consider it a full deadlift, and it is much less taxing on the lower back....
Rack deads work too......]
aS DOES TAKING ONE WEEK OFF FROM DEADS
As does holding it in the lockout position for a few seconds...........just somethings that worked for me.....rest, recovery and food!
