The rack deadlift is great for lifters with less range of motion, but can also be used to work the top range of the deadlift with a heavier load.
Typically, the rack deadlift is set up with the bar just below the knees, but just above the knee is fine too. If you don't have a rack, use a few 45 pound Olympic plates to elevate the bar into position.
