Look at videos on YouTube about bracing correctly when you’re lifting. Yoga has helped me a lot, I’ve been doing the program that kneesovertoeaguy wrote up as well. As a few others have said, increasing mobility in your hips, strengthening your core help tremendously too. One tool that has helped me a lot too is a psi-rite, another guy that I follow online is squatuniversity.
