It's more useful to get form checks on sub-maximal lifts. Your hips are rising without your back, forcing you to stiff-leg it for most of the movement.
I think it looks fine. You may want to take a second before the rep to take a breath and pull the chest up more.
Not sure if srs. My size=10 stone 10lbs, almost 11st (for the British) 175cm or 5'9" 184kg lift (for British ppls) It is probably 95+% of my max, what's a good %for form checks? I noticed my hips go up more on super heavy pulls, I keep them down easier with ~85%
I was serious, are you quite tall? I genuinely thought you were lighter. Even still thats heavy lifting for your size. Oh just saw 175cm.
Yeah, not that tall, maybe compared to powerlifters in my weigh class. I have strong back with tiny arms and legs, spider build lol.
Hard to tell from the angle but it looks like your shoulders are a little forward when you started the lift. And just like what others said, your hips rose too soon which caused you to almost stiff leg deadlift the weight.
