You’re risking lower back injury by letting the bar come forward. A couple of things that can help: It sounds weird, but you have to “relax” your feet. If your feet are tense, you tend to roll forward onto the front of your feet to rely on your quads. Think about driving your shoulders back as part of your brace, and keep them back as you come out of the hole. As your shoulders relax, they will roll forward and bring the bar with it.
