How to sit and stand up in pregnancy?

No proper way but whatever you do, we try to tell patients to straighten their back while standing up to reduce strain and trauma to the back. So even when it comes to picking things up when you're pregnant, it is best not to bend your back forward but to squat down with a straight back then pick the item up. Essentially, just normal back care. You shouldn't be bending forward when sitting and if there is back strain, you can have a stool and prop the legs up to feel better. To relieve back strain, you can lie down and put your legs up in a 90 degrees angle. This can also help reduce swelling of the legs for people with very bad water retention.
