I just started Strength II in NROL which has me doing rack deadlifts for the first time. I thought I would be able to do more weight with the limited range of motion, but I couldn't pick the weight up on my first attempt. I ended up doing the same amount of weight for the rack deadlifts as the regular deadlifts.
Can anyone provide some help on how to initiate the lift?
I'm used to regular deadlifts with my hips back and "pushing my feet through the floor". However, I could get a feel for it lifting the bar off the rack.

Thanks in advance!
