If you are too big to get a good pull, then you ll have to forego this one and concentrate on the traditional deadlift off the floor. You will not be able to use as much weight for this deadlift as you normally do with the pull off the floor due to the increased range of movement. Go up in weight slowly from there. As with any deadlift, begin the pull with your legs while keeping your back as flat and erect as possible. Keep your arms locked straight during the lift to completion.
Application is last on the list.
This deadlift variation can be substituted for regular deadlifts in the off season up to about 6-10 weeks prior a contest. At that time, you can return to regular pulls off the floor with, hopefully, increased power throughout the lift. For lifters who need less time to convert over to their normal style, they can stay on these a little longer. For lifters who choose note to rely totally on this variation in the off season, I suggest doing a down set of off the block pulls after your regular deadlifts. Sumo deadlifters can use these also and may actually benefit more than conventional pullers.
