Flexion Spasm

Hello,

I read Ester's book back in 2015, have practiced her methods since and have returned to the book often whenever I feel the need for a refresher! Despite my work, over the last few years I have developed increasing back spasm whenever I go into flexion. Sometimes it makes sense, flexing over quickly to pick up my dog and not hinging, but more concerningly, when I roll over in bed and go into flexion temporarily, or when I am lazy and flex my back in the car and try to get back into a healthy posture. Sometimes the spasms are crippling and take me out for a week, but most of the time they are just quick spasms.

It appears that my body has forgotten how to go into flexion. The way I interpreted the book, especially the chapter on hiphinging and exercising, was that a rounded back should be avoided when bending over and doing ab work. So I never flexed, and now when it happens naturally, I often into spasm in my QL area.

Everyday movement involves flexion of the lower spine as well as extension, and I am afraid that I demonized flexion to the extent that my brain kind of freaks out when it happens. 

Any advice? I would say that I have an anteverted pelvis that tends slightly more toward ATP when I get sloppy....

Thanks!
