Deadlift Weaknesses

Good morning all! When I am doing heavy deads, I know that if I can get it to the knee, I can complete the lift. What body parts do I need to work on/are weaker in the chain to improve the floor - knee section of the lift? Any advice on improving them or this segment of the lift?

I don’t like giving advice because I am insecure, but that is where I am weak as well.

I find paused deadlifts and deficit deadlifts helpful. :slight_smile:
