“How do I stretch my back?”

The best way I found a stretch my back on a daily basis is to lie on my back, bring my right knee to my right shoulder as if I'm aiming it to hit it. Then I do the same on the left, then I bring my right knee e towards my left shoulder, again aiming it is if it could touch and repeat left knee to right shoulder. Hold each of these positions for 30 seconds. I'm too lazy to count to 30, so I count six long deep steady breaths and each time I breathe out I feel my muscles relax a little bit more each time. I do this in the morning before I get out of bed and in the evening when I get into bed to prevent sciatica. Good question, thank you
