Focus on squats as upright as possible, even pause back squats; DLs or halting DLs focusing on that posture/balance from the floor to the knee and/or upper thigh; and full pulls - if you do flat-footed pulls, that will reinforce the habit of not continuing to drive up w the legs as you extend the hips at the top. Remember that driving with the legs does not inherently mean being slow at the top - it means more force directed upward and more elevation on the bar.
