Actually - looking at that, your upper back is slackening off, too.
But hey, I haven't deadlifted in a long time, so this could be rubbish.
The only thing I notice is literally just before you pull, your butt drops a touch but curls round ever so slightly (those tender glutes)
at what point is the amount of rounding so small that its insignificant?
I dont question that i round during the lift but as can be seen in that still, is that a smaller issue then its being made out to be, and actually there is something else funtamentally wrong with my lift?
I don't see anything crazily wrong other than the pre-setup, looking at my vids I'm hardly flat backed
noOK setup needs fixing then.
I've repeated myself several times on this issue, if you chaps want to continue to chase your tails then go for it.
There is actually a later video where he addresses setting up from the bottom with Dianne Fu. The top down set up is more aimed at people who lack the proprioception to find neutral spine with hip flexion.Hehehe... I love this video, as it offer no insight into how anybody who's ever been an Olympic lifter trains with straps.
