Pulls are the first part of the movement, they are like a deadlift with a shrug. See the video tutorials in the pulls section.
People often make the classic mistake of doing pulls on too heavy a weight, resulting in slow laboured pulls that do not sufficiently mimic the classical movements. Therefore I recommend not doing pulls on more than 105% of your 1RM.
Pulls are to be done for sets of 3-5 reps. At least 3 sets of pulls is required for the appropriate stimulus with 5 sets being optimal depending on how intense the earlier session has been.
