Cool – love seeing videos. Some initial observations:
a) kill the straps; not only would I suggest they aren't as helpful as you might think, but also they cause you to be in a semi-squat, semi-kneeling position for like 15 seconds before the lift; that's not priming your deadlift; if nearing your max load and grip is failing, try chalk instead (I've got an article coming up on chalk) or if not allowed at your gym, use alternating grip
I've tried…
My hands are so small I can barely even touch my fingers together when gripping the bar. Alt. grip works if it's not very heavy and for low reps, but that's counter productive… I used to use chalk in high school, can't use it at work though, unfortunately… I've been trying to work on this for years, but even the normal grip strengthening techniques pair with gloves don't do a whole lot of good.
b) go for fewer reps; deads aren't so much about endurance, so I'd re-start with the classic 5x5 approach; stop reps as soon as your form deteriorates
Thanks here, I'll keep that in mind.
c) I haven't seen this much before, but you are extending your knees way early in the lift
That is what I was talking about earlier. It was the first thing I noticed and it's because my arms (in particular) and legs are so long that when I don't do that I can't stand up, lol. The bar and my hands are actually stuck below my knees and I can't straighten my legs because the bar stops it. The only way to avoid it is to shift my weight forward onto my toes, not too good for injury prevention. This I think is my biggest issue. If I get my knees closer for DL power My bar gets stuck; if I widen my legs the bar doesn't get stuck, but I lose tons of power and my arms are WAY too wide apart.
d) do those shoes have a lot of cushion? I'd try with just socks;
Actually, no. That's why I bought them.
e) try pulling back more; I personally have a really hard time with this cue myself, but if you focus on your heels and pulling backward, your shoulder blades will stay behind the bar
Again, I go out of my way to do this, but then the bar gets stuck below my knees… Actually though, if you watch my feet close enough you MIGHT be able to see, but I was actually picking my toes up off the ground for a few reps just to make sure my weight is on my heels.
f) your lower back is doing an odd "pop and round", especially on the last few reps; you want to keep a nice natural arch throughout
Only noticed that on the last rep, thanks. :)
g) your chest is out, which is good
That's easy. I have unnaturally tight rhomboids. I actually have some minor nerve impingement I'm working on. Needless to say, shoulder retraction, unlike most people, is easy for me.
h) try to keep your head/neck in one position throughout the lift
I'll try. That should go for pretty much any lift though.
Also, for practice, I do speed deads once a week – low weight, 5 reps, but with explosive speed and perfect form. That has helped me keep good form during the heavy days.
I was previously doing the plyometric dead lifts my last workout. They really helped, they were only only a freemotion cable machine, for time reasons, though. It's a good machine, but not the same as on the bar.
