Didn't see anything on search, feel free to lock if I skimmed past it.
I've had horrible posture for years, with only mild scoliosis, and I've tried lots of different tricks to try to teach myself to sit up straight - with no avail. I can only sit up straight for a little while and then my back starts to hurt. I'm wondering if there is a good workout that helps with it, or some tricks anyone has used that help you not forget to sit up straight.
