Knees coming in on deadlift?
 

Anyone else have this problem? will post comparison video Monday to show exactly what i'm referring to.

Looking at your video you are starting hips up, head looking down, back semi-rounded. This is putting your shoulders too far forward, so when you pull your body is trying to find some sort of leverage to deal with this.

This will cause your feet/weight distribution to do odd things, and perhaps you are rolling in a bit on your inner foot.

I would recommend focusing on a Rippetoe style RDLs instead if you want to work hammies on a deadlift, lowering the bar along your legs until your lower back wants to break.

Try that and see what, if anything, your knees are doing - just for comparison.

I'm no expert on this subject, but with the shoulders forward like that you are really putting yourself in an awkward pulling position.

Like BtB suggested, but you could also do halting deadlifts. This really imrpoved my legdrive and pull from the floor, in a very short time!

swede-that looks like it would help quite a bit, thoughts on rep range for the halting deadlift?

I do them in set of 5, and usually i work my way up to a top set for the day, using 4-5 sets of 5.

I also find it a very good way to work my grip, so I mostly use a double overhand grip on those, and paus for a sec before decent.

Good luck man

i was thinking 5's, but possibly to a top (submax) weight for 2-3 sets

Good idea! When I started to do them, they made my lats crazy sore the days after from squeesing the bar towards the chins. It turned out to be one of my favorite assistance lifts for the deadlift since it really gets pull from the floor nailed down. When a deadlift fails, formwise, it all starts with a bad pull from the floor (bar to far from chins, hips moving up before bar etc)

well whenever i miss the lift either my mind isn't right or its at the bottom of the knee, due to poor positioning and a shitty pull

Caused by weak hips. Try some banded monster walks:
