Oh, thanks. I hope it helps you get a PR :)
About the knees going forward:
This is taken from an article in a Swedish lifting magazine. Its written by my coach who has the national deadlift record.
Look at the picture to the bottom left: Knäposition, Knee Position.
His position in the left example is what you want.
See how knee tracks forward so the shins are brought to the bar, not the other way around. It results in a more upright torso (= less back strain) and his hips are closer to the bar (= better leverage), than in the right example where his shins are vertical. The right example is unfortunately often tought in online deadlift tutorials. Its a worse style for the vast majority.
Wow, thanks for going out of your way to hook us up with this. Now, besides having the knees over the bar, are there anything techniques he teaches that differs from what the online Gurus teach?
