Sticking up the Centopani video is an apples and oranges comparison to the original video and the key point initially made re:that technique.
The initial lifter is clearly not strong enough through his thoracic spine to take the weight straight off the rack and maintain good form. Centopani clearly is.
It is much more effective to get your set-up and form right from the floor, which is key for most, if not all lifters who post here.
I don't agree with the touch'n'go technique for safety reasons. When developing lifters see a video like Centopani, haven't developed the strength, they deadlift like that and just hurt themselves. Pulling from the floor, when you click and really feel like, is just this magic connection and feeling of power & explosion through your hips, which probably negates how much you feel your back actually working.
The simple reality is you're not going to pull from the floor without using your back.
Yes, I am trying to correct you, since inclusion of the Centopani video changed the context of this thread and previous comments.
