I have video!
So, as some of you may remember, I’ve set a goal of a 500 DL by the Dec 31, 2009. I’ve successfully rackpulled 475 from a low shin position. But I can’t manage to get 455, or even 445, locked out. I get it to above my knees all the time, but no further.
Meat, here’s what I hope will be some diagnostic video. Apologies in advance for the repeated closeups of my fat ass.
For the first several lifts, my belt was a notch further out than I’m used to. I hated it that way on squats Friday, but I thought I’d see how it was on deads. By the time I got to 350, I couldn’t stand it and had to take a break and readjust it (I brought my screwdriver as well as my camera today!)
3@275 (70% of 90% of my est. max), conventional, loose belt: - YouTube
3@310 (80% of 90% of my est. max), conventional, loose belt: - YouTube
1@350(90% of 90% of my est. max), conventional, loose belt: - YouTube
1@350, conventional, straps. I switched to straps because my grip was going on that first 350: - YouTube
1@350, sumo, straps, tight belt. At the end of the last video, the looser belt, which I hated on squats, was also starting to tick me off on deads, so I took a short break and moved it back in a notch to where I usually have it. I switched to sumo both because I wanted to give you a look at both my DL variations, and because at heavier weights, I feel much stronger on sumo: - YouTube
1@405, sumo, straps, tight belt: - YouTube
0@445, sumo, straps, tight belt: - YouTube
My 455 (which I didn’t try today) looks and feels identical to the 445 attempt here.
If it’s not obvious from the videos, I’m pulling the bar into my shins. I was bleeding through my sweats from today’s session. 
My estimated 100% 1RM is 430. Am I just overreaching? I’ve pulled 425 from the floor without much more trouble than 405, and as I mentioned earlier, I’ve rackpulled 475 from the bottom of my shins.
I feel these mostly in my lower back, and I realized today most of my accessory work is upper-back focused. Besides GMs and GHRs, what else could I do to emphasize my lower back and help break through this plateau?
Thanks in advance for all your excellent advice, Meat.[/quote]
your form on both conventional and sumo are pretty good. i would definitely get ride of the gloves and the straps. the gloves have NO value whatsoever when it comes to lifting and straps should only be used on weights wayyyyy above your full ROM max. the grip needs to stay ahead of your pulling strength. get some chalk if you can use it in your gym. if you can’t get a resin bag… not as good as chalk but better than nothing.
i would like to see you attack the weight more. you go into each lift and just slowly start pulling. you always want to move a weight as fast as you can while mantaining good form. the momentum that is created by lifting fast can push you through sticking points. so… get in the habit of lifting that shit as fast as you can- warmups through the heavy sets. obviously as the weight gets heavier, the bar will slow but if you get in the mindset of always moving fast it will become automatic. the hips through part should always be very forceful.
start throwing in some speed work at the end with around 50% of your max for sets of 3 reps for around 6 to 8 sets with minimal rest. you could rotate these in every other week or so.
there’s a saying that to get good at deadlifting, you shouldn’t deadlift. what that means is that if you constantly pull full ROM you will fatigue your CNS and actually get weaker. i would make things like GM’s, rack pulls, speed pulls, zerchers, RDL’s, front squats, hyperextensions, etc. the core of your lower work for deadlift. i would only pull heavy every
4-5 weeks or so.
as for lower back work, front squats and zerchers are my favorite. lately full ROM zercher squats are my favorite. also GM’s off pins and good morning squats are in the rotation.
