Not bad...a few points.
1) Finish your reps...all of them, early on you do not get your shoulders back, but seem to do a better job toward the end.
2) When putting the bar down, put it down in the opposite order that you picked it up. Bend at the waist, when bar clears knees, bend the knees. (You unlock the knees, which means you need to move the bar around your knees to put it down. That puts the bar forward at the end of every rep, which is why you keep moving forward.
3) Bar appears to be forward of the midfoot slightly. Bar should be in contact with your skin the whole way up.
4) When are able to get the bar down in the orginal spot, hang onto the bar for a set of 5. This is more like a set of 5 quick singles.
