Bringing Up My Deadlift

what are some ways i can improve my deadlift both at the first portion, bringing the bar up past the knees, and the second part of locking out?

im guessing rack-pulls would help with the lock out but as for actually getting the bar past the knees what can i do to improve?

sorry i just saw a thread very similar to this one, i didnt see it before. my bad brahs.
