This technique alone has stopped me waking up with back pain in the night (though there is still some aching in the morning). Wonderful results.
However, I find that the small of the back needs some extra support. I tend to put a sock under it, which seems to help a little, but not totally. Is this something to be worried about? It does sometimes seem to help a little as well if I put cushions under the knees as in the video - however, I find this unfomfortable, and usually wake up in the night and have to remove them.
Is there anything else I can to do support the small of my back while stretchlying?
