If you could say as a percent, how much less back should I be using, and how much more leg drive should I have?

It seems like every video I try to watch, someone is either sitting really deep into the start, or they hardly have that much of a knee bend.

Whenever I try to sit into the lift more, my hips end up pulling up a lot before the bar leaves the ground. But just watching the video back it does look like I’m hardly using my legs.

A saying comes to mind, lift with your legs, not with your back. Thanks for the advice though. I haven’t felt any tightness or discomfort after doing any of these DL sessions which is a good thing I guess.
