American Bone Health has a workshop on Spine Health: https://workshops.americanbonehealth.org/courses/spine-health-workshop-2021/
For house cleaning, maintain a straight, not curved, spine. I read somewhere no lifting more than 10 pounds, and hold things close to the body, not with arms extended far out. Don't sit down heavy in chairs, use a controlled movement. I've also seen some guidelines for sneezing, like put your hand on your chest for support.
