Most statistics say that back pain during pregnancy resolves on its own within about three months after giving birth. It's no wonder because the main protagonist is now lying in a crib! But not having back pain doesn't mean that all the issues that created it during your pregnancy have resolved.
It just means they've resolved enough that you don't have back pain right now. As you've seen, your body doesn't necessarily bounce back on its own. You'll need to take specific steps to correct many of the changes that have occurred to your pelvis and spine.
Many women continue to have increased lordosis (natural inward curve of the lumbar and cervical spine) years after giving birth because they didn't retrain their spines to adopt their normal posture, or they didn't know to stretch the tensor fascia lata (TFL) and quadriceps muscles to restore normal pelvic position. Correcting both these issues will expedite abdominal strengthening by restoring the muscles' normal length and tension. Taking time to work on these issues now can prevent future back pain as well as help your tummy-toning program.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
