I think mrthingy has it right.
It's probably worth dropping the weight for a few weeks and really exaggerating a flat back, even if it takes a couple of seconds to reset between reps.
thats what ive tried to do...thats where the 'boucing' was coming from. Trying to force my hips down which I thought would straighten me up. Ill try working on the top part too..with really low weights.
I can't really see much wrong with that if I'm honest, it looks pretty good. On the first rep the bar is too far away from you but the rest are fine on this front. It looks like the anterior part of your hips are tight from the fact that you have a bit of lumbar extension at the top of the rep. Spend a good amount of time stretching them thusly

Can you describe what kind of back problems in as much detail as possible?
I already do lots of glute and lower back mobility work..buit theres a few things there I could add in.
The problem, kinda hard to explain..I strained a muslce a few years back in the uper left glute..feels like it right in my ass bone most of the time. According to Chiropractior when I saw a few years back..it froze up my left hip/pelvic joint and stopped it moving properly/freely...so over 3-4 sessions they worked at getting the joint moveing properly again. It took ages to start squating etc again, but when ever I tried to deadlift it felt crap, so i left it out until about 4 months ago. A few weeks back after a leg session, i got up out of chair and it went again, probably just out of stiffness and being an old bugger now
It done this a few times last few weeks and again ive been for some treatment where they are just trying to slacken it up and get it moving. I do the tennis ball and roller thing on top of left gluite along with lots of stretching but at the moment its very dodgy. So I think its a case drop the weight big time and keep working on it
It was bad today after doing 140 x 5...last rep something went, which is why I posted vid, to see if I was doing anything crazy stupid..or if its just a probelm I have i need to deal with. I can drop the deads if its going to cause too much grief again, but I dont want to drop squats etc. At the moment..it will affect these also.
