I started doing them today, i can barely put up 110 on the bench for now, because i only weigh 129, but i had no problem doing 145 deadlifts, that is if i was doing them correctly. I felt a lot of pressure in my lower back, but no pain at all. I did 5 sets of 5, and between each rep, i put the bar on the ground and waited like 2 seconds, (Don't know if you are supposed to do all reps in a row, or put the bar down each time), also, if i can lift a ton more than i can squat or bench press with the dead lift, does that mean i am still doing it correctly?
