Deadlift Form Check

set of 5@8
my last few reps I was rocking back on my heels at the top.

My lower back looks rounded but it feels flat, I think this is just fat?

For the single at the end was I focused on pulling the weight out of the bar before the lift to get my chest lower and back straight, but it ended up looking the same.

For the most part it looked pretty good to me.

Have you considered starting with your hips closer to the ground and increasing your back angle?

Nice pulls. Sounds and looks as if you are not pulling the slack out completely. I would cue your “chest up” without dropping hips height and see if that works for you.
